Trying to install https://www.quaddicted.com/reviews/qbj_1.05.html the Injector fails to uncompress the ZIP archive and shows the user a message "Couldn't open file! invalid compression method".

No idea what might be wrong there. The file is "compressed" with "store" but I would assume that other files in the archive were using that "compression" already and I am not aware of issues.
