I have recently purchased a Win 11 Laptop, I downloaded the Technic Launcher and Tekkit Classic, then copied the %appdata% from the 10 machine to this one, hopefully the attached screenshots will be able to show what the problem is, I've also copied the log, which means nothing to me.
I have read a couple of posts from last year with the same/similar problem, both were told to downgrade their graphic driver, don't want to do this before confirmation it's the right thing to do.Technic Console.txt
