@sandro
I don't quite understand what you want to tell me? As you can read in my first post i've already set the permissions for the whole programm and the whole folder where the image and setup files are stored to read/write for all users (even guests). Or am i doing something wrong with this?
EDIT:
I've managed to solve the problem. I used BatChmod to set all user permissions to read/write and unlocked the fuolder and all sub items. Now it works with every user.
