A question that I am unable to solve.

Operating System: Windows XP SP1
Burning Software: VERITAS RecordNow DX, Version 4.11
Anti-virus Software: avg
DAEMON Tools Version: none. Yet.

Hello.
I recently installed the Alcohol 120% demo, but it did not meet my needs, so I uninstalled it.
I would like to try Daemon tools, however every attempt to install a similar CD emulation program has been wrought with failure.
I cannot get Windows to recognise new virtual drives at all. Everytime I try to reinstall any divers, it tells me that the drivers are invalid. Is there any way to remedy this?
Thanks in advance.

Check in device manager what drivers are installed (if any) for the virtual devices.

So I installed Daemon Tool 3.47 now and I think I could explain my situation best with a picture.

I find this odd because I have full administrtive privleges on my computer.
If I try to install any drivers, I am told that they are invalid, no matter what type I try to install.
