Hey,
Just now, I found that when the Avast is on, some of the games cannot be opened.
More specifically, Game can run and the process can be found in the Task Manager. Nevertheless, it will disappear without a reason. The problem can be resolved by disabling Avast.
When I say the game in this post, I am specifically referring to the
Dragon Age 3, a game sold on
Origin.
Please see this post, who encountered the same problem.
