Adobe Acrobat Pro 12 serial number maximum allowed

[Edie5FCE]

I have Acrobat Pro 12 installed on several computers (same serial number).  Some of those computers don't exist anymore, so I can't deactivate them.  I reached out to Adobe support, but they can't help because it past the end of life.  Does anyone know how to clear out the allowed computers of the nonexistent ones?

If you don't see them there, either, then I'm afraid there's nothing that can be done about it.
