Actually, I recognize those files you DO have: they're the ones contained in the Update pack.
For some reason, you are missing all code files contained in the Main Contents Archive.
Are you sure you are installing with all THREE files from here in the same folder? Make sure you DO select the "Main Files" option.
And don't rename any of those 7-Zip files; they need to have their appropriate filenames, otherwise the installer doesn't "see" them.
Can you also check the size of your entire PotC installation folder? I'd quite like to know if anything else is missing.
