On Windows 7 there’s no such problem.

I included dxdiag and launcherlog
Hello again!
Based on your DxDiag, I only see an onboard GPU. Does your laptop also have a dedicated one? If so, what type? Please make sure the drivers for that card are up to date. In addition, please make sure that your system is set to use the dedicated card when trying to run the launcher and any associated programs.
I check for updates and used the dedicate card but I still get the same error
Hello again!
Based on my research, you will need these drivers to update your Intel video card. COuld you update then attach your newest dxdiag?
