Vista: Disable the Digital Driver Signing Enforcement
By default, Vista requires digital drivers to be officially signed. Sometimes you can work around this issue by turning the enforcement off. Here’s how to do it.
Warning: This may allow Vista to install a driver that will make your system unstable. Frequently, disabling this check still will not get the driver installed.
That being said, if you are desperate to get a driver installed, this is certainly worth a shot.
Likely this option will be removed before the final version of vista ships!
Turn off Digital Driver Signing Check in Vista:
1. Create a shortcut on the desktop to cmd.exe
(this recipe explains how to create a shortcut if you don’t know how)
2. Right-click on the shortcut and select Run as administrator
3. When the command window opens, type or paste the following and press ENTER:
Bcdedit.exe /set nointegritychecks ON
4. Reboot and then try installing the driver.
