Hi ,

Could you post your dxdiag (system specs) and the full log file?

Troubleshooting Guide - The Launcher fails to load or crashes on load

Hey Ballard, I fix the problem.

Thanks. :slight_smile:

I’m glad you got it working. Please feel free to post an answer if you have the time. Just in case other users run across this issue.

Just video card that didn’t support DirectX, now I change my video card and that’s ok.
