Forcing the installation of a driver on Vista



Sometimes, the installation of some drivers is blocked on Vista, that means that you couldn't use your device correctly.

That problem is because Vista stops the installation of non signed drivers. You have to disable the signature verification during the installation of the driver.

To do so, follow these instructions :
  • Start menu > Run, then tape 
    bcdedit /set nointegritychecks ON
  • Restart your computer, then reinstall the driver which had the problem ;
  • Undo the stop of the verification by using this command on Start menu > Run 
    bcdedit /set nointegritychecks OFF
  • Restart the computer for the last time
