The weird thing is, after changing the .net framework settings, the games worked, but only through the EA Download manager, so I don't think it's a directx problem, I also have the direct x sdk so I have a tottaly updated direct x . It's something else, but I won't know if the games still work after reboot until tommorow, because I have shut down the pc because I'm going to sleep soon.
But I really find it weird that i have this problem, while I almost nowhere can find a similar problem, and I don't have troubles with other programs, didn't try other games yet. It's some kind of .exe problem I'm sure of, because neither shortcuts to .exe files nor the .exe files themeself can start the game, only the EADM can open the games, and I can only hope that that will stay now after the last adjustments.
Even more strange is the fact that the .exe file of GTA IV does work, only i get a WS10 error.
