Hi,

On a fresh clean Windows 8 image, my software driver (signed) installs fine and shows up properly in the Device Manager. However once i uninstall it , subsequent reinstalls show up as 'Unknown Device' in the Device Manager.

From the device details, I find that it refers to /looks for the .inf file in c:\windows\inf folder but the file itself is missing from the location. The FileRepository has all the required files. But trying to update from there also fails.

Could anyone help me with troubleshooting this problem. What could be going wrong.

Thx,
Gita
