Things that worked with my win 7 pro 64bit:
Turn off windows 7 "User Account Control (UAC)"
Set gp4.exe
and gpxpatch.exe to run "as an administrator" in "windows xp sp3"-mode.
There is no nead to do so with csm.exe!
Include csmcore.exe (and sometimes csmprocess.exe) in your antivirus program's ignore-list!
You should have a smoothly running game!
