Recently one of our copies of Microsoft Office 2010 seems to have lost it's registration and now
when the user accesses any of the applications it states that the product is not registered.
I have attempted to manually enter the MAK key and have gone into the Help menu to change the
registration but when I go to activate it it comes up with an unspecified error 0x80070001 and
will not register. I have done a full uninstallation and made sure there was no other Office product
to interfere with the software. Office 2010 was working fine up until about a week ago.
