Monogame OpenGL Game crashes on some Windows 7 computers

I'am learning some Gamedevelopment using Monogame.

I started a Windows OpenGL Project and everything works fine on my Win8 machine.

I have compiled the project and sent it to 2 People, both are using win7 x64 and one of them can't open the Game.

After that, I tested it on my other computer (also win7 x64) and I get the same problem, the game process starts, then the screen flashes (Aero seems to deactivate), then everything gets back to normal and the process of my game crashes without a message.

I'm sure, that there is no problem with my code, maybe some missing dlls but most of them are copied with the game

• Lidgren.Network.dll
• MonoGame.Framework.dll
• OpenTK.dll
• SDL.dll
• Tao.Sdl.dll

Okay, I fixed it using an OpenAL32 installer, following a solution I found here.

You have to install it if your game doesn't work. Fixed it for me on my second computer.
