@baRa @xXxSmeagolxXx @tk[as] Was anyone of you doing some tests to figure out why the game-doesn't-start bug happens? We need to have this fixed and without your help we can't fix it since we can't reproduce it.
Does the bug also happen if you go into your game folder and start "Warcraft II BNE.exe" directly rather than using the shortcut on your desktop?
If using "Warcraft II BNE.exe" to start the game doesn't help, try to open "Warcraft II Config.exe" and change your renderer. Now try to run "Warcraft II BNE.exe" again
