So I've been wanting to show this game to my son for some time now. And then it pops up on sale today. So I bought it and downloaded it, then installed it.

However, every time I click play from the GOG interface absolutely nothing happens. If I run task manager, it shows up there, but doesn't do anything else.

I'm running an intel core i3-4005U CPU @ 1.70 GHz with Windows 10. 64bit.


Right now I'm feeling very swindled.
