I have tried pretty much everything others have said, and nothing...starts to launch, circle curser appears, screen blacks out and I am back at Steam.

After so many years I decided to play this wonderful game again, but I found a problem that my towers do not shoot at the enemy by default and only I stop the attacks from direct control. At the first levels it is not difficult, but then... Has anyone encountered this? How to solve it?...

can we have a camp tower or something that spawns infantry?

At first I thought it was games for windows live, then I thought it was the games resolution bugging out. But NOPE. It has to do with too many cores!!! In task manager I limited my cores to 4 and it worked!!!! Does anyone know if there is a stream/properties launch command I can insert instead of globally limiting my CPU to just 4 cores out of 24? 😂...

On god, it doesn't even launch. It just shows a black screen while a command prompt in the background kicks off 1000 error messages. I've verified the cache, installed on multiple drives, etc, and it still refuses to launch. Is this because GFWL shut down? If so, I'm calling bulls- and claiming fraud. I bought the game. I should be in working condition. It is not. Shame on the devs for no end of life plan....
