When you try to install a new hardware device on a Windows Vista-based computer, Windows Vista cannot install the driver for the hardware device successfully. Additionally, you may sometimes receive the following error message:

Windows encountered a problem installing the driver software for your device. Windows found driver software for your device but encountered an error while attempting to install it.
Device_Name

This problem occurs if the Infcache.1 file that is in the %Windir%\System32 folder is deleted or corrupted.
