When I encounter a problem that doesn’t really have a concrete solution when searching online, it gets frustrating. I still haven’t found a perfect fix for this issue, but I am able to get by for now.
I upgraded to Windows 10 a few months ago and didn’t have many issues. The games I wanted to play worked just fine, as did everything else. Then recently I tried to play Far Cry 3, and it simply wouldn’t run when I double-clicked it from Steam. (More specifically, my Steam avatar would become green-bordered for a few seconds, indicating I was playing a game, then return to blue.)
