After you use the Last Known Good Configuration feature to start a computer that is running Windows Vista or Windows Server 2008, some .inf files that have been serviced may be deleted from the %windir%\inf folder.

Note: These .inf files correspond to the drivers that are included with Windows.

If you try to install a new device that uses an .inf file that has been deleted, you may receive an error message that resembles the following:

Driver not found

If you try to reinstall the same version of driver that was originally serviced, the devices that use that .inf file may not work correctly.

Consider the following scenario:

• You have a print server that is running Windows Server 2008, Windows Vista, Windows Server 2003, or Windows XP.
• You try to create Point and Print client driver download packages for drivers that have multiple operating system .inf files.

However, the operation fails because the Internet Printer Protocol (IPP) does not support this functionality.

The information in this article applies to the following configuration(s):

• Catalyst Display Drivers 6.6 and above
• All-in-Wonder X800 GT series
• Windows XP Professional
• Windows XP Home Edition
• Windows XP Media Center Edition
• Windows 2000 Professional
• Windows Vista 32-bit
• Windows Vista 64-bit

Symptoms
When installing Catalyst drivers version 6.6 and above, users may get a “severe” error stating that the “INF error video driver is not found”.
