Game Rendering

Hello, does anyone know how to render/export a game that was made in blender? I have tried saving the file using the game engine runtime addon, but I get an error message when I try to open the .exe file that says: "Runtime error! This application has requested the Runtime to terminate in an unusual way. Please contact the application’s support team for more information. Any help would be greatly appreciated.

The addon included with 2.60 had some issues with bundling Python. You could try the 2.61 beta to see if it behaves better: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.61

I would rather not have to download another version of Blender. Is there any way to fix the problem, or is there another addon I can download that will not cause this problem?
