Hi trancesnail,
The Launcher and the editor will run on Windows 8 64bit. I looked at your dxdiag and it seems the issue maybe with your graphics card. The only one listed is your integrated graphics card and we recommend having at dedicated DX11 compatible card as well.
You can find out more about our recommended specs here and if you would like to compare/discuss specs with other users you can do that on our Forum thread here.
Cheers,
TJ
