I was playing the game and decided the add a mod to the game. I installed a mod ı activated it but ıt doesn’t activate and ı get this error while ı started the game please help?
We saw this just recently. In that case invalidating the Steam cache (or re-installing the game) fixed the issue.
The odd thing is ı didn’t installed via Steam the direction to the game is : C:\Program Files (x86)\Game Dev Tycoon
Hmm. that is odd. Actually, this isn’t even the latest version. Can you let me know where you got the installer from? Perhaps we made an incorrect update.
ı just typed the google “Game Dev tycoon dowload” is that a mistake ? or might be cracked
yea, that’d explain it 
If you purchase the game legally, that issue should be gone.
oh. ı noticed now that is cracked ı just thought this is a free version of the game sorry
Just to prevent any further misunderstandings, there is no free version of this game (apart from the DEMO) so please support us by buying our game legally.
