I installed windows professional 64 in virtual box with the cd patch and microsoft .net framework 4. I then installed capitalism lab launched and got a black screen with audio. the same thing happened in windows enterprise 32... I tried something and it fixed it... what did I try.. I went to compatibility mode and set it to 640 by 480 and set run as administrator... I then launched the game and it kicked out the black screen and pushed it to work properly....
I then disabled the 640 by 480 resolution setting and it still worked ok... I rebooted and the settings stayed...
