I have got the same issue.
Red Alert2 is running fine in Crossover and I can even play online via XWIS. But I can not get the Launcher to work. I installed net framework 4 and xna framework 4, but if I start the launcher (CnCNetYRLauncher.exe) crossover wants to install it again and crashes at the end (critical error). I attached the logfile.
Thank you in advance!
