Beta installer - Disclaimer
This installer is in beta, so there might be bugs. I don't take any responsibility for what might happen to you or your computer by using it. You may wonder why I don't wait to release until it's stable. The answer is simple; I need your help to be able to make it stable. Since I'm no super mega corporation like NVIDIA I don't have the range of hardware to test on. So if you want to help me beta test, you're welcome to play the part for Guinea Pig!
