I haven't had any problems with windows 7 since I did this :) I now use windows 8 but I used 7 until last month. Just try to do it again and make sure you do every single step :) hope this helps ya

I am having same problem and have carefully followed your steps as outlined now two separate times. I also did a cmd line tool to find orphaned drivers and devices and removed them all before a third unsuccessful attempt at your fix. boooooo. I am stumped and at my wit's end. This all started near the same time as a failed install of my cellphone drivers. I uninstalled those but had no further need of either phone or usb devices, so no problem noted afterward. The beginning of this recent issue is due to my Microsoft Mouse (an older usb cabled mouse) right click button failing to work. I bought a new wireless mouse and keyboard to install and now get the failed to install warning. All other efforts to fix have ultimately led me here.
Thoroughly stumped. I can uninstall my old mouse, and it will reinstall correctly. Nothing new will. The new Mouse/USB button/Keyboard install just fine on my other PC running WIN XP.

Thanks for any ideas
????

edit: the link to the cmd line tool (sic) is included for clarification of what I did there: How To Easily Remove Old Drivers from Windows

Well, I would advise you to open a cmd prompt as admin, and run "sfc /scannow". Let it run and reboot. Sometimes this works like a charm. If it doesn't work, maybe I would tell you to grab the windows 7 installation disk and try to use one of the repair tools. After all that and since we aren't going anywhere, the last option would be reinstall everything: backup your files, format, clean install and that will for sure remove any existing problems. You could install windows 8 though, it's much much better than 7, all the drivers are automatically installed just perfectly! :)

thanks for that, but unfortunately it didnt work for me..
is it possible that a pc wont support 2 usb mouse at the same time as i am afaraid that if i disconnect the old mouse first and then connect the new one, some corrupt file may create problem even for the old mouse to function. thats y i am connecting both the mouse and trying to use the new one unsuccesfully. if u have any other ideas pls do post.

thanks.

apoorv90 - I tested that on my other PC and my laptop. The USB mouse had no problem running simultaneously with the other mouse on both ...

Well, I tried the unplug ALL and restart method. Nice. For whatever reason, the PC did not like that so it reorganized all USB drivers, assignments, everything. I plugged in the new wireless mouse and keyboard. BAM! Worked right away. Thanks for all the help Will file this one away in my memory hole for future reference ... have a feeling won't be the last time

Hey there! I had this same problem too! untill a while ago! It's very frustrating! I spent days on it! So, I will make your job easy by telling how to solve this. This was the way it worked for me!

Here's the solution for the ones who might have this problem:
This worked for me in Windows 7 Ultimate 64bit!
You must have all administrator privileges!

1- Open Windows Explorer

2- Go to C:/Windows/System32/DriverStore

You will have a couple of folders and files.
You will have *.dat files and other file named: infcache.1

3- Right click every file (dont touch the folders!) and choose properties.

4- go to security tab

5- click Edit

6- choose your account and check the box: full control (see ss)

7- Click ok.

8- Repeat to every file

9- Select all the files (*.dat and infcache.1)

10- Press shift+del

11- Press OK.

12- Now, go to C:Windows/System32/Driver Store/File Repository/

13- Search for folder named usbstor.inf

14- Open it (if you have more than one, choose the most recent)

15- Copy "usbstor.inf" and "usbstor.PNF"

16- Paste those two files to C:/Windows/inf

17- Reboot your pc and voilla! :b

If Windows doesnt install them automatically go to device manager, uninstall all unknown devices and the ones with the yellow exclamation mark, then click in "check to see if there is any hardware changes"

Now, Windows will install all your hardware successfully :b



Did it work?

i made this steps but still during the installation it says that FAILED.
pls help.
