Based on some topics about this same problem, if your have the AIR application installed on your computer, you need to uninstall it as this application is no longer supported.

A bit bewildered as there is no Acrobat version 2.x update available.

Pehaps you are working with Adobe Air?
If so, you may want to post at the Adobe Air Forum.

I get the same prompt whenever I open Acrobat, and then the same error. And it is indeed Acrobat, and those are the version numbers referred to, both present version number and update number.

Are you sure it is not an add-in like Flash Player, Air, or Forms Central?

Adobe AIR is at version 2.

The version of Acrobat might not be that important.
