If the user is trying to install games from an archive, they might need a tool that can extract the PS4 disk or decrypt digital purchases. However, Sony's security prevents this. Tools like PS4 ISO Mounter can be used, but again, this is only for legal copies. The steps would involve using a tool to decrypt and mount the ISO, which requires the user's own license files and the correct keyfile, which is not publicly available and legally obtained only through the PS4's system.
