After 4 seconds Fixed the problem with the 2nd Schwarzesmarken game. Follow these steps: Mount the disc for the 2nd game. Copy the entire content to a separate folder. Mount the disc for the 1st game. Replace “error_avoid_inst.exe” from the 2nd game with the one from the 1st game. Execute “error_avoid_inst.exe” in the 2nd game folder. Ignore the errors, and just click OK until you get to the folder screen. It will now display correctly. Install the 2nd game from the folder. ??? Profit. Just FIY: you cannot skip the OP the first time it plays. Also, you cannot uninstall the game using the “inst.exe”. You must use the file from the 1st game.

Forgot a step: also copy the files "GMfc.dll" and "UnivUI.dll" form the first game folder to the second game folder.
