Determine if driver is installed

[AbqBill]

Hello all,

I'm working with UltraVNC 1.0.1 on Windows 2000 and XP and the following driver file versions:

setupdrv.exe - 1.0.0.17 - 8 July 2005
vnccom.sys - 1.0.0.17 - 3 March 2005
vncdrv.dll - 1.0.0.19 - 10 June 2005
vncdrv.sys - 1.0.0.17 - 3 March 2005
vnchelp.dll - 4.0.1636.17 - 3 March 2005

Currently, this is how I check if the driver is installed:

1. Check for registry key: HKLM\CurrentControlSet\Services\vncdrv
2. If this key exists, check file version of %SystemRoot%\system32\vncdrv.dll

If the registry key does not exist, or the vncdrv.dll is less than version 1.0.0.19, then assume it's not installed. (Is this method correct?)

This seems to be a lot of work. I think it would be very useful if the setupdrv.exe could be enhanced to write a singular registry value to indicate successful driver install and uninstall.
