Done all the fixes besides .net 2.0, I tried running the 2.0 dotnetfx.exe from microsoft, says I already have it, but I did not do custom search thing yet.
Still crashing in lobby and loading, and in game as well with runtime (trap) error. My vista business machine crashes less then XP, but still crashes, with the same error.
Next up, the .net update, will try that and after some runs post results.
