Driver update for Windows Vista x64 (64-bit)

Windows Vista x64 requires that all the drivers have the digital signature. If any driver does not have a digital signature, Windows Vista x64 is not loaded until the driver is removed.

How do I know which protection version is installed for the application I use?

Of course, the old protection driver versions without Windows Vista support did not have the digital signature. Therefore, launching the old protection versions for Windows Vista x64 should be performed as follows.

  1. Launch the protected application with the rights of administrator.
  2. Allow driver installation
  3. Reject reboot (otherwise the OS will not load in Normal mode)
  4. Update drivers
  5. Reboot the OS.
