This is an error message generated by Windows (code 0x5 is Access Denied) due to not having the appropriate Windows Administrator rights, or the file regsvr32.exe is missing from the Windows operating system.

Make sure you are logged on as a Windows administrator with full access rights to the Windows registry and that UAC is disabled.

If this is the case, check that the file regsvr32.exe is present.

Lastly, check that your anti-virus/spyware/firewall software is not preventing Driver Genius from updating the Windows registry.
