Ok. I played a bit with this error and now I understand maybe a bit more what happend.
I extracted this project into a new folder and then for the first time I run foldit.bat.
It tried to create this ini file in C:\winnt\ directory. The problem is that I just have read access to this folder. After this the programm crashes and windows offers me to debug it.
Can I change this behaviour somehow ? Is it possible to create this ini file in the same directory like the rest of this programm ?
