Seems that the code is not universal.
although I have downloaded it and installed it step by step as per the documentation file. some of the main features is not working(which is essential for the website function).
seller requested my Cpanel access to resolve the issue, which I'm not willing to provide .
also the code checks for authenticity with the sellers website and for some reason that is not working as well, and returns a message that I need to add the license key (although it is already added).
Accordingly I have ended up with punch of php files and no website.
