Game Maker Community HUB/Game Maker 6 on Windows Vista
From YoYoGames Wiki
Game Maker 6.x is incompatible with Windows Vista natively. This is due to the zlib compression that has been done on the Game_Maker.exe and the Game Maker runner, which cannot be uncompressed in Vista.
Making Game Maker 6 Games work on Windows Vista
Mark Overmars created a Game Maker 6.1 Converter to allow Game Maker 6.1 games to work on Windows Vista. The converter does not convert the game to a Game Maker 7 game, however, it replaces the zlib-compressed runner file of GM6.1 with another GM6.1 runner file that is uncompressed. This causes the size of the executable to gain an addition 1 MB, but zipping the executable will compress most of the gained size.
Making Game Maker 6 work on Windows Vista
In general, it is believed that Game Maker 6 does not work on Windows Vista. However, there exists a proposed fix that has not been widely confirmed to work, but it worth a try:
- Navigate to Game_Maker.exe
- Right click it, choose Properties
- Go to tab compatibility
- Check "run this program in compatibility mode"
- Set drop-down box to win98/winME
- Check disable desktop composition
- Check disable scaling on high dpi settings
- Check run this program as an administrator
