Build working only on some PC

Hi everyone. We have a serious problem with our Unity project. It's impossible for me to build correctly on my laptop but it works on my computer. For some unknown reason, the scene is completely black (but musics and sounds are working ) or even worst, the game crash immediately. That's one problem but we need to made a web player version and we have the same problem. We build on a PC, we host it, we can play in browser with the link but it doesn't work on my computer. Anybody has an idea to solve this ? https://googledrive.com/host/0B7cQ1bDbjVlWRVpMQWRoUzBXMnc/Web.html Here's the link to the web version which is working only on one PC.
