Hi, it should work for Windows 10 and above. I haven't tested for Windows 7, however.
For the white screen bug, can you confirm if it does the same thing on a newly created project folder? I have updated the Windows & Mac installers for what I think is causing the problem. Please download v.1.0.1 and get back to me with your findings. If it's still causing the white screen error, do send a screenshot of the contents of your project folder.
