Hi ludo, i tried run the demo from http://www.winscop.com/install/WINSCOP_GS_113.EXE Is that the program? It crashes differently for me. It suffers from bug http://bugs.winehq.org/show_bug.cgi?id=14861 If know how to compile and patch wine, you can comment out the code mentioned in that bugreport, then the installer finishes fine
