install? there is no install, only a compressed archive that you need to store on your hard drive.
can you post an error screenshot or logs?
Thank you for your answer, I am a bit confused I am not tech-savvy and English is not my primary language, I'm sorry about that. I guess my problem is that I automatically dragged the file to programs and I'll try without doing that. The Error Message is simply that the program can't open, nothing else (Maybe bc it is not a program and I am stupid)
