Both experiments came to the same end. Page not shown on, 1st Intend the clean download, uploaded to a folder and installing to a brand new database as 2 other DB where not found, or not good enough. Result: a greyed out filed with Admin page not found, Meaning instead of the admin login, a greyed out area saying page not found. Shop Url Page not found. Similar result.
After deleting everything I tried a Softaculus approach, with the exact same results.
