Anybody got real help from technical support with the "game won't start/open" problem?
I have GreedFall on my two computers with different OS versions (Windows 8 and 10), really powerful machines and the game doesn't want to open on either of them. And unfortunately the support is in fact "support".

You're not giving any detail that might point to the problem. Check the forums on the game's official web site.

I had the same problem and my laptop comes with GEforce Experience.. I disabled it for now and then I went to C:\Users\Owner\Documents\GreedFall something like this and removed all the saves there and the "graphicconfig" after that I run the program and it worked again :) or just open the "graphicconfig" text file and change the videomemory? or that one with abnormal numbers to 0. Hope this helps

Necro-posting for future reference for the solution... I already posted a solution in a previous thread, I hope this helps!
