I assume you already had DirectX redistributables installed aswell? Or maybe you didn't and after buying the game and launching it on Steam it automatically got installed on your machine in the background. If that isn't the case then maybe it's the anti DRM solution ( there is just one .txt file and it seems to bypass the protection for most people ) that's at fault here.
I guess the more this happens to others the quicker we will eventually find out what's the culprit behind this odd behavior of the game
Yeah youre right to assume that i also have DirectX redistrubatables, but as for the DRM solution where can i find this, I mean for the game itself like this one
