Upgraded to win 10 and hw1 classic refuses to launch now. Think hw2 classic also does the same.
Do you have a nvidia or amd videoadapter?
Nvidia gtx 670 with latest drivers. Why. Its just a win 10 issue I guess that needs patching its not a hardware issue I’m thinking. I.e it worked in win 7 then didn’t when I updated to win 10. Classics fail to launch but RM versions boot up ok.
Try reinstall game.
