First of all, thanks for your inputs on this.
I did not installed the .net framework, just run that code to check wich versions were installed.
Gameex Evolution worked always fine, i installed it several years ago so no new installs, 4 years or more ago, and it was only now that the bug presented itself.
Mind you that last time i fired up the software was 4 months ago or so, and then when i started this thread, so something in that time frame must have changed.
Please don`t remove it, i like it much more than the "normal" gameex and i bet a lot more people are on the same pace.
It´s just a "bug" if you press ok on the error it will go away and the software works like it should, it`s just my "nerdiness" on the subject eheheheh.
