My iTunes Playlist Not Found

Product: iTunes version 12.1.3.6 (Special issue to enable continuous use of iTunes with Windows XP, service Pack 3) Issued September 4, 2015)

Issue: Unable to activate iTunes, even after clicking on acceptance of software agreement and initiated attempted library search.

Troubleshooting Steps Tried: Restoring computer to an earlier date. Doing Disc Checks on all discs. Computer search for iTunes downloads/installations (found, reinstalled, but still not working beyond aforementioned point)

Futile results to locate version on Apple website.
