Adobe Presenter 11.1 tab not showing up in PowerPoint

Recently I had disabled the Adobe Presenter Add-in in PowerPoint. When I tried to re-enable it, nothing worked. I even tried all 6 solutions on Adobe's help site.

What finally worked was going into Programs and Features, finding Microsoft Office, clicking on the Change tab (or right-clicking and choosing Change), and doing an online repair. Eventually Office was reinstalled on my computer.

When the Office installation was complete, I clicked on Start (Windows), searched for PowerPoint, and then Ran PowerPoint as an administrator. Voila! The Adobe Presenter tab now appeared in the ribbon.
