Win 7 software issues?

[#1]

I figure we're going to get issues with software on Windows 7, and as quite a few of you are geniuses what better place to put software we're having issues with!  Plus I know some of you use the same software so may have solutions
Daemon Tools version 43.04 Lite - Windows pops up incompatible message - Seems to work though, mounts an ISO.
Nvidia Drivers 191.07 - Can't run performance assessment tool, bugs out on DX9 test - May not be driver, don't know (8800GTS)

There were known compatibility problems with Daemon Tools when Windows 7 first hit the scene. I abandoned it then and installed Gizmo instead.

I was using Daemon tools on the RC with no issues, its just retail that is bringing up the incompatibility warning.  It works fine, maybe its just something I did.

I'm using the 64-bit version, my memory fails me but the problems might have been specific to x64 variants.
