I installed as admin, installed DirectX 9.0C, set witcher to run in Compatibility Mode for XP, and created a shortcut with -dontForceMinReqs.

I tried to change to windowed mode, but the instructions on the forum don't match what I actually see in regedit.

I get the error "The Witcher has stopped working"
