GameStarter is a application to launch a blender game without blender install. The user can setup parameters of blenderplayer with a GUI. it is available for all major operating systems.
I think that is coming soon integrated in Bzoo game.
For this I wrote a batch to make the installer. I used NullSoftInstall and py2exe for integrating extra python modules.
If you are interessed by that you can customize this for your project:
