ADB Device Not Found! :(

OK, posted this in the Q&A section with several responses but no real answers. Figured I'd post it here before another section where it might get locked or moved.
Anyway, ADB was working fine until a few days ago. Now it says "error: device not found." Fastboot still works just fine. I've tried everything I can think of to get it working again. I've uninstalled and reinstalled the usb drivers, removed the Android SDK from my PC and reinstalled, wiped and reflashed my device, made sure Debugging is on, and tried getting ADB to work on all 4 of my PC's. All running either Windows XP or Windows 7. No dice. Can anyone help? Thanks in advance.

The other day it took me about an hour to remember to just turn on usb-debugging and plug it in to the usb drive. I kept going to the fastboot screen instead. Maybe that's your problem too?

Thanks for the reply. If you read my OP you'll see that I've made sure debugging is on. In fact, debugging is also enabled by default after a wipe and clean flash. Unfortunately my problem isn't as simple as enabling usb debugging.

Have you gone from one phone to another? When I made the switch from a tmo->att n1 I had to remove ALL drivers before installing them again in order for my phone to work.
Perhaps try removing ALL drivers and starting fresh?
In Envrionmental Variables, create a System variable:
variable name: devmgr_show_nonpresent_devices
variable value: devmgr_show_nonpresent_devices
With your phone not plugged into your pc, go to device manager and under the View menu, select "show hidden devices".
Remove everything under ADB. Remove anything in unknown devices that says Nexus1 or Android, or Google. Remove the Composite Devices under USB (they will be added back upon reboot if the system uses them) as well as the Mass Storage Devices.
Reboot your system. Plug your phone in and update/install your drivers for your phone.
I used both the drivers from the sdk and from http://forum.xda-developers.com/showthread.php?t=613217 to have fastboot and adb functional.
Good luck!

Thanks for the response. I'll give this a shot when I get home. FYI, I didn't change devices. Same Nexus One I've had for the past month. Just one question: When you say,
"In Envrionmental Variables, create a System variable:
variable name: devmgr_show_nonpresent_devices
variable value: devmgr_show_nonpresent_devices"
I don't know what this means. Where can I access this? Thanks!

Just a thought but are you remembering to boot up the phone as normal?
As in not into fastboot, etc.
This stumped me for a few hours.
I kept trying to "adb" while the phone was in fastboot or recovery.
Sorry if I'm teaching you to suck eggs.

Followed all of these directions, reinstalled the driver, and I still can't connect via adb. Still getting "error: device not found." Help!

Try to download the latest Android SDK and have it installed again. Also download the USB drivers within that package...

Done and done, days ago. Still no dice. This is ridiculous.

Still having problems. Tried everything I can think of, and everything suggested to me by the XDA community. I don't know if this will help any of you guys help me, but when I type "adb devices" into a command prompt, it returns:
* daemon not running. starting it now *
* daemon started successfully *
List of devices attached
And then shows nothing. So effing frustrating! EVERY computer I have (I actually have tried it on 6 different laptops and PCs) returns the same error and cannot find my Nexus One. WTF happened!? HELP!

I'm sure you're trying to be helpful but, if you've read through this thread, you'd know that I've already done all of that. OBVIOUSLY, I've done all of that because, like I said, ADB STOPPED working. In order for it to stop, it must have, at some point, worked just fine. And it did. It worked perfectly until recently. So, yes, I've installed all the damn drivers I need. But, no, it's still not working. It's infuriating.

debugging mode os on? did you open adb, delete all htc drivers then reinstall them from the sdk. not just install them but delete and then reinstall.

also once in bootloader your good, some instructions say go into hboot, not for me, just right in bootloader, not hboot.

Do you see this device ( pic ) @ device manager :
If you do , there is no reason for adb commands under DOS prompt for not workig well ... really weird

I need the MTP driver for Windows XP. I've gotten the other 2 drivers up & running, but not the MTP. Anyone able to provide a link for a working MTP driver for my Nexus 7?

I guess you have to install Windows Media Player (this is only possible with a genuine Windows).
Personally I use AirDroid to transfer files. ( https://play.google.com/store/apps/details?id=com.sand.airdroid )

I already have Media Player 11 on there. No go.
AirDroid isn't an option as we only have WiFi at work on our outside LAN and our computers are all behind the firewall.

i had this issue recently.
do you have USB debugging turned on? if so, turn it off.

Yeah. No luck.

@mrhomiec
Yes, I turn USB debugging off and try re-installing the driver again and it is working fine now. Many thanks.:good:

After ages trying to root my Nexus 7 and repeatedly un/re-installing of drivers using various 'toolkits' and then finally succeeding, I was upset to see this problem in Device Manager.
Seeing mrhomiec's excellent solution in the first thread I looked at was a great relief. Many thanks!

Media Transfer Protocol Porting Kit
I know this is super old but just in case anyone searched this for help, You might try downloading the Media Transfer Protocol Porting Kit
Heard this works. If you Google search "Microsoft MTP" it will be the first result. I can't post links so that's the best I can give you guys.

MTP working with XP
Here is what I had to do to get MTP working with XP SP3:
1: Download and install MTPPK12
2: Download and intall Media Player 11
3: Connect the N7 to the PC via the USB cable and set USB to MTP instead of "Camera".
4: Open "Settings" and turn off "USB debugging".
5pen "Device Manager" on the PC and look for "Android Device". If you find and entry for an "ADB" device, uninstall the driver. Unplug the N7 and plug it back in. The PC should now find a device titled "Nexus 7" and install the driver. Open "My Computer" and "Nexus 7" should now be listed and ready to transfer files.

A little something to get USB-Debugging working
Hey guys,
for those who want to use their precious Android with enabled USB-debugging at a Win XP system:
1. get some drivers that work fine without enabled debugging (for HTC disciples: http://forum.xda-developers.com/showthread.php?t=2191279 ) and install them.
2. switch your device to usb-debugging and look up the exact hardware-ID @ your device manager (device manager -> android device -> details -> hardware ID) - keep that window open for you'll need the exact key
3. Search the installed drivers (for me it was C:\Programme\HTC\HTC Driver\Driver Files\XP_x86) and edit the 'androidusb.inf'.
4. In the file, look for the 'Device Section' and scroll way down to the 'For XP and later' section. Here you copy the first entry and paste in your hardwareID.
For me, I took:
%USB\VID_0BB4&PID_0C01&MI_01.DeviceDescRelease%=HTCAND32.Dev, USB\VID_0BB4&PID_0C01&MI_01
Click to expand...
Click to collapse
and changed it to:
%USB\VID_18D1&PID_2D02&MI_01.DeviceDescRelease%=HTCAND32.Dev, USB\VID_18D1&PID_2D02&MI_01
Click to expand...
Click to collapse
5. Next scroll down until you find the '[Strings]' section. Here you do the same thing as before:
Copy the first entry and edit it according to your hardwareID.
For me, I took:
USB\VID_0BB4&PID_0C01.DeviceDescRelease="My HTC"
Click to expand...
Click to collapse
and changed it to:
USB\VID_18D1&PID_2D02.DeviceDescRelease="My HTC ONE"
Click to expand...
Click to collapse
(you are free to name it what ever you want )
Next you'll need to scroll down until the patten changes from
USB\VID_0BB4&PID_0C01.DeviceDescRelease="My HTC"
Click to expand...
Click to collapse
to
USB\VID_0BB4&PID_0C01&MI_01.DeviceDescRelease="My HTC"
Click to expand...
Click to collapse
here you'll need to copy the first entry again and edit it to match your needs. Just copy the device name you have entered before.
6. Finally you can install the drivers manually via your device manager. Just choose your pimped androidusb.inf as driver and you should be able to work with your android phone at usb-debugging (for example for MyPhoneExplorer).
Of cause I am not responsible if you wreck your Win XP / your drivers so don't overdo it. If you don't know what you are doing, do it like the Beatles and 'let it be'

MTP and ADB come hand in hand so if anyone wants to use the ADB-interface, he or she can do so by following this little tutorial and don't even need to spam their system with unnecessary bloatware.. sorry, but I don't see the problem you've got with that ?
And I'm very sorry, I don't understand the problem you've got with a useful tutorial but that doesn't mean that I've got any problem with you oO
So, no offense

My problem is that most people searching a thread like this aren't going to read every post. They go to the "last page" to see what the latest solution is. Your post was on the last page by itself and I was concerned that noobs reading it would think it was "the best" solution. I wanted to point out that the post previous to yours actually had an easier solution. And, IMO, Media Center takes a miniscule amount of disk space compared to what the vast majority of people have available.

Well I have found this thread because I was looking for a solution for the MTP / ADB-problem and thought that other users might find this missing information useful. Your problem with my post would mean that you disagree any discussion or even better solutions to problems (threats) as soon as you posted your solution .. which truly isn't the way a community works.
And sorry, but I won't discuss the cancer-like spreading of MS products to any system with you in this threat. It's not as simple as disk space.
I suggest we now stop bloating up this topic, unless you've got more useful information concerning the problem.

Nexus 7 not showing up in Windows

Okay, So I bought this new Nexus 7 about a week ago. It was used but the person I bought it from was trustworthy. It came pre-rooted and unlocked. Anyways, my Windows 8 laptop WILL NOT recognize it no matter what I do.
Let me start off by saying, I am no novice to Android. My main device is a Verizon Galaxy s4, and it was the S3 before that. Both phones I did lots of modding and theming on them, and always running a custom rom. I have adb installed and working on my computer as well.
Now the problem. When I plug in my Nexus into my laptop, nothing happens. It doesn't make the usual windows device plugged in sound or anything, and it doesn't show up as a drive in Windows explorer. Even if I open up the device manager and then plug in my Nexus nothing shows up. Not even the "device not recognized" thing. Nor do I get a notification in the Nexus statusbar saying it's plugged in as a media device.. Though the battery DOES charge.
I have tried enabling usb debugging and toggling back and forth from MTP to PTP and still nothing. Tried it w/out USB debugging as well. Nothing.
Tried plugging it in while in fastboot.. Nothing.
I even downloaded the Google drivers through the Android SDK manager and since it doesn't show up as any device in device manager I can't uninstall them and update with the new drivers. This is soo soo sooo frustrating. Obviously it was able to connect to a computer at some point because they rooted and unlocked it, but now I get nothing. I've tried 4 or 5 different computers, Windows 7 AND Windows 8. And even more USB cables.
Can somebody please please shed some light on this?
It's soo frustrating not being able to use ADB with my new device or even do simple file transfers. Right now I'm using Airdroid to move files around but it's agonizingly slow and worthless for moving big files like Roms and whatnot.
And before you say it.. YES I have searched and found no definitive answers even though I KNOW other people have had this problem.
Someone help please?

C'mon... Somebody..:? Anybody?

Try this. Plug it in via USB as you would. Then unlock your nexus 7 and it should up, works for me lol.

Tried this too. I've been using the new factory cable and it doesn't work. I've tried five different cables and different usb ports. Also tried factory resetting and different roms as well.

Couple of things to try:
1 - Go through Device manager (Start -> Right Click My Computer -> Manage) - And remove anything and everything to do with Android, or Nexus etc.
2 - Plug in device, if nothing happens right click The top of "Device Manager" - Which should be your computer name - And click "Scan for hardware changes"
If this doesn't work, try to download WugFresh ToolKit, and install the drivers through his ToolKit, I had issues like this when I first got my Nexus, trying all different things and random drivers, my only way to fix it was going through WugFresh toolkit and downloading his drivers. CLICK HERE FOR THE TOOLKIT
Good luck

Thanks alot man. I do have Wigfreshes toolkit, i just haven't really done much with it. I will try all this when I get home though. Sounds like a good method to try. The device came pre-rooted and unlocked, all I had to do was flash recovery through goo. I'm running Vanilla root box night lies and they are great. I'm just really worried about getting in a bootloop or softbricked since there is no battery to pull, and i can't connect to my computer to unbrick. If it happens I'll be waaaay up the creek with no hope for a paddle.
Thanks alot.

Here is the latest Android Composite ADB Interface Driver straight from SDK instead of toolkit.
http://d-h.st/kDu
If you are worried about ROM failing, installing MultiRom is highly recommended. Not indifferent to partitioning a hard drive and installing multiple operating systems on a PC, MultiRom is indispensable when experimenting. If one ROM doesn't boot, simply boot from another or to your stock rooted.

This is soo soo sooo frustrating. Obviously it was able to connect to a computer at some point because they rooted and unlocked it, but now I get nothing. I've tried 4 or 5 different computers, Windows 7 AND Windows 8. And even more USB cables.
Can somebody please please shed some light on this?
It's soo frustrating not being able to use ADB with my new device or even do simple file transfers. Right now I'm using Airdroid to move files around but it's agonizingly slow and worthless for moving big files like Roms and whatnot.
And before you say it.. YES I have searched and found no definitive answers even though I KNOW other people have had this problem.
Someone help please?

Haha, thanks for the help, but I wish it were that simple. It was a first Gen Nexus7 by the way too.
I'm no novice to the ways of Android, and i tried everything under the sun to get it to work. Nothing Would make it show up on the computer.
Anyways, it just ended up turning off one day (with a fully charged battery too) and wouldn't turn back on. I ended up calling Asus and they repaired it for me. It had a burnt out USB port. They fixed it and it's up and running fine now.
Long story short, be careful what you buy on eBay one, and two, Asus has EXCELLENT customer support. From the day I called them to the time I got it back fully repaired only took 7 days exactly. And I didnt have to pay for shipping. If you ever have a problem with an Asus product don't hesitate to call them.

I just solved my problem. The Nexus 7 was not showing up in the device manager and windows explorer. Once usb plugged it would charge but do nothing.. In device manager I found "ACER Composite ADB Interface". I googled it and this is the problem. apparently Windows update install this thing but it doesn't work with the Nexus 7. You have to uninstall it (don't forget to check the delete from computer box or else it will reinstall itself). Then look for this : ASUS Android Composite ADB Interface Driver 8.0.0.1 for Windows 7 64-bit and download it.(sorry I can't post links)
Now with your Nexus 7 plugged in update your driver by selecting the browse my computer option and locate the file you just downloaded and there you go it should work. After months of searching it's finally working. :victory:

[Q]PC cannot detect my Nexus4

I use the Stock ROM, Kernel, when I plug in the USB, there are nothing happen in my PC.
I've tried differen USB port, different cable and different PC. i can charge, but PC cannot read my Nexus
Also, I've tried to enable and dsiable the USB debug, the MTP/ also useless.....:crying:

I know this issue. Sometimes my PC also wont recognized my Nexus. I switch between mtp and ptp a few times while connected to the pc and and plug the cable in and out and after some times it works again.
But to be sure, all necessary driver are installed and there is this sound, when you connect the nexus to your pc?

Try this:
Plug your phone in. Find it in the device manager (look for the yellow triangle). Right click, and choose "Update Driver Software ...". Choose "Browse my computer for driver software". Choose "Let me pick from a list of device drivers on my computer". Scroll down and pick "portable devices", click Next. Choose Standard MTP Device > MTP USB Device. When it warns you that things may go tits up, click yes anyway.

Have you tried to do a factory reset? If not make a backup and go for a try.
Backup without a USB connection can be done through bluetooth (sloooow) or Wifi (much faster than bluetooth). I like to copy large files to/from my N4 with ES File Explorer.

A thought just came to me: have you tried to look for the device while it is at the bootloader screen or at recovery mode?
If not, give it a try:
note: while at the bootloader screen the touchscreen does not respond, this is by design – or lack thereof. to manipulate you can swith options with volume up or volume down and choose an option with the power button. to quit this screen use the volume rockers to choose "Start" or "Power off". The former will resume the normal boot sequence while the later will, as you should expect, turn off the device.
1. turn off and unplug the device, if it is pluged.
2. hold down volume down and power. keep holding until it vibrates or you se the big open android with lots of text information. this is the bootloader screen.

You should be seen something like this - Nexus 4 bootloader screen​
3. now plug the device to the computer. it should recognize the device and eventually install/apply some drivers.
If that happened and the device got recognized by the PC you can do the next step: go to the recovery mode. To do this follow on.
4. using the volume rockers choose the "Recovery mode" option and with the power button choose it.
You will see something like this - Nexus 4 stock recovery mode​
If that happened you should get the device recognized again and new drivers installed.
If this happens we will be very close to be able to use the USB to copy the backup to the PC. Let us know if all goes as planned.
To quit the recovery mode just press and hold the power button until the device turns off, 5 to 10 seconds.

I've tried before. no response......
So I'm pretty sure that the USB function is gone....

got to admit it sounds like there are some good ideas here but you seem to be sure that your phone usb port is done. Ok if this is the issue you can always use ES File Explorer and share the folder you want on your pc and use the LAN function on ES explorer to transfer files over wifi.
Secondly I had a similar issue and download minimal adb and fastboot which found drivers for me to use adb on my phone which again will help you transfer files. Hopefully you dont respond to me like others with I tried that already.... LOL

yes I think my USB PORT is done too. so I decide to repair it by myself because the fee is about HKD $200...:crying:

In case you want to give it one last shot i had a similar problem when i first purchased my nexus 4.
The first time I connected it to the PC (Windows 7) I had USB debugging enabled and it recognized it (I.E made the sound when connecting it and started charging it) but could not access the storage via MTP or Camera. When turning off USB debugging I could access it as a camera but not as Media storage. I kept installing and uninstalling the USB drivers in windows. Eventually after many attempts causing frustration to build up, I clicked on cancel on the installing drivers and to my amazement the PC recognized it as MTP and I could transfer files. To this day I continue to use the same configuration and have not touched the drivers.
I don't know how or why this worked, I just know that it did.
Good Luck.

Samsung Windows drivers problem

Looking for some help please, with my new-to-me S5. I want to root it, mostly so that I can restore Titanium backup from my S4, but probably to install CM12 too. I have installed (and uninstalled, rebooted, installed, rebooted, many times) the latest Samsung drivers e.g. Samsung_USB_Driver_v1.5.51.exe, I have tried installing Kies3, I have tried different USB cables, I have tried my Win7x64 laptop, my wife's Winx64 PC; none of them will show the phone in Windows Explorer.
I did try it on a very old laptop (Core solo) that happens to have a play copy of Win8.1, and it worked! I then tried to use Odin v1.85 and Odin v3.09 to push CF-Auto-Root, and it always ended with Odin "Not responding" - presumably because the laptop doesn't have the guts.
I did put Win10 preview on a spare hard drive in my laptop, but no joy after installing Samsung_USB_Driver_v1.5.51.exe. Under Win7 I had tried older versions of the drivers too.
Ant bright ideas please??
TIA

Kies will install the correct drivers so uninstall Kies completely, reboot your PC then install it again, check for updates and if any update kies then run it.
When it is running plug in your phone to a USB port that is directly on the PC not via any hubs and you must use the cable that came with the S5, other cables will not work correctly, make sure it installs the drivers at this set up.
Windows does not necessarily install the correct drivers, you need to go to My Computer > properties >. device manager and find your device in the list it should be shown as Android Mobile Phone if that is there then make sure the installed drivers are Samsung Android ADB Interface, if it isn't showing this driver them change it.
The other option if you have the Samsung drivers installed is to plug in the phone check in Device Manager on your PC and find your phone then check and change the drivers.
Turn off any firwall whilst you do this as that can block the device as well

Thanks for the suggestions. Yes, I had tried the original Samsung cable as well as others. Plugged straight into a ThinkPad, no USB hub.
Uninstalled Kies and the Samsung driver package, rebooted, installed Kies, checked for updates (none), and - Nothing. Nothing in Device Manager, nothing in the Safely Remove Hardware tray applet. Nothing in the notification area of the phone. The firewall was disabled for all of that post-reboot.
It's driving me mad...
I do eventually get a USB Device Not Recognised popup with Unknown Device shown in the window. By now, there is also an Unknown Device showing in Device Manager under Universal Serial Bus Controllers. I could Update Driver, but unsurprisingly Windows can't find one. My only other option would be to use the Have Disc option, but only if I had the right .inf file... :crying:

"None of them will show the phone in windows explorer"
You know you need to put the phone into download mode to use ODIN?
It won't show in explorer when you do that, but ODIN should say it is connected
And use the latest version of ODIN you can find, 3.09 should work, 3.10.6 is latest

Thanks for replying. Yes, I have tried plugging in with it in download mode and using Odin, but it wasn't showing the COM port, so it wasn't recognised using that either. I even tried pushing CF Auto Root, but of course it failed.

It sounds like the cables you've tried are faulty, so long as the phone USB port is not
Multiple PCs say to me it's not a PC issue
The samsung drivers just need installing with the installer, don't worry about manually installing them, once you have working USB cables/port it will install them automatically so long as you ran the installer

Have you attempted to use different USB ports on the computer you are using? Contrary to what Detection has said, the fact that you can get it working on another computer with all of your cables does point to this being a PC problem and not a cable problem. My suggestion would be to completely uninstall Kies, keep it uninstalled, use different USB ports and allow windows to install the drivers itself.
On various occasions, removing Kies has worked, and on another it was the USB port that I was using that was the problem.

OP said he tried two different Win 7 PCs before trying the 8.1 laptop on which he had partial success
My guess is if he is constantly moving the cables from PC to PC, if they are faulty, bending them around is possibly making the connection by the time it ended up on the laptop it recognised the phone from, like when your charger cable breaks inside and you have to wiggle it around to make a connection
But as he also said, it failed to work even on that - so that's 3 machines, one partially recognised the phone - Id say the chances of it being a bad USB port over 3 machines, or even bad machines are very slim
Bad phone USB port or bad cables is my guess
Either that, or Win 7 isn't playing nice with the phone/drivers

I remember reading somewhere that with windows 7, you have to run odin as an administrator......also remember reading that it's not just the firewall you have to disable, but the anti virus as well......It may not help to uninstall kies as this *may* remove the Samsung drivers. Probably be better to leave it installed, but to use windows task manager to kill any running kies processes before you start odin up, as (from what I've read ) kies will interfere with odin.......
And for info.......odin 3.09 is the version I have successfully used on my phone.
Sent from my rooted kn0x0 stocKK SM-G900F S5

Thanks for all your replies while I was asleep.
I have used multiple USB ports on the 2 Win7 machines, multiple cables including the one that came with the phone. When I dropped the firewall, it was f/w and AV as it's one program (Symantec) (corporate laptop, not locked down). I have tried running Odin as administrator. If it wasn't for the fact that it did work on the ancient Win8.1 laptop, I would have thought the problem was with the phone port, but I could see it in Windows AND Odin displayed the COM port - it was just that Odin then went "Not responding"... which I assume was a system performance issue...
I will have another try tonight with yet more cables and I must have some USB ports I haven't tried yet... None of it makes sense and I am not a noob.
Edit: This is all having a negative effect on my laptop too - I used to be able to see internal and ext SD on my S4 in windows explorer - at the bottom of the right pane it had i9505 then you saw a folder for each SD. Now I just see ext SD as a drive letter.

Try this:
Install or just use the portable version of "Ghostbuster"
http://ghostbuster.codeplex.com/
Unplug all USB devices from the machine other than K&M
Run Ghostbuster as Admin
On the first device listed of each section, right click and choose "Add Class"
That should highlight the entries in that class and flag the ghost entries
Do that for every section until you have them all highlighted
Now click "Remove Ghosts" at the bottom and let it do it's thing
That will remove all non connected USB devices and their drivers
Once it's done - reinstall Samsung drivers just using the normal installer
Plug phone in and see if you get any better luck with it being detected

Thanks Detection, I hadn't come across that before. It deleted LOADS of ghosts... ...but unfortunately it hasn't moved me on at all. Still nothing in WinExplore, no COM ports in Odin. I am somehow jinxed, or rather this S5 is.
Edit: Just did it all again with a couple of reboots for luck - no better.

Open up the Device Manager on your PC then plug in your phone and look for any new connections to appear in the USB controllers list there may be Unknown device or another named device if you see a new connection unplug the phone and check the list again to see if it has disappear from the USB list, if you see a USB device appear and disappear from the list as you unplug and plug in the phone this is the one you want.
Right click on this and select Update Driver Software, click Browse My Computer then click Let me pick from a list, if you have the Samsung drivers installed on your PC you should see one or more called Samsung Mobile USB Composite Device, select the most up to date version if you have more than one listed and install that.
If you don't see the Samsung USB drivers un-tick the box that says Show compatible hardware, scroll down the list to the left and find Samsung Electronics Co Ltd, there will be more than one, click on each one until you see Samsung Mobile USB Composite Device in the right window, then click on that and install it.
You will get a warning saying that changing the driver may cause the device to not work properly just click OK and install the driver, if it works the USB device in the list should change to Samsung Mobile USB Composite Device.
Try this and see if it gets you sorted manually but don't forget to make sure you have installed the Samsung drivers on your PC first

There are a couple of things you can try as Windows is preventing the installation.
1. Control Panel > Devices & Printers then plug in your phone and you should get an Unknown Device appear, right click on it and select Troubleshoot and run that process to see if that sorts out the problem.
2. Start your computer in safe mode then try installing the driver manually that way, then reboot your PC normally.
I had this error message last year with something I was trying to install but I can't remember just how I sorted it out.
