Hi Oldman7,
Thanks for posting the new files. Please try the recommendation in the Flash Player | Windows registry permissions tech note, but use the reset_fp15.bat.zip file I posted previously, and take heed of the warning on the page, before proceeding. You'll definitely want to back up your system, create a System Restore Point, and back-up the system registry (although this last item is not mentioned in the tech note).
Essentially the 'failed to register' error is being returned due to 'access denied' permissions errors (for both you and Vinix Wu). The permissions need to be repaired fro Flash Player to register.
