Yes, i installed it by downloading that file and extracted the content in to my program files folder, then ran the processing.exe that is in there.

Thank you, indeed i wasn’t aware processing creates more dirs on 1st startup. I now deleted all dirs and installed freshly, but that didn’t change anything -.-

Ok, i switched to Java and tried a simple print(“hello”); as well as the ribbons example. The same error occurs in both cases, just like with the python mode.
