VBA - How to detect Acrobat core API vs. Adobe Reader

Question

I'm working on a VBA project and want to have PDF editing included as an optional function. I know that editing and saving PDFs is restricted to the Acrobat core API, but I can't seem to get VBA to differentiate between them.
My reference library is using Adobe Acrobat 10.0 Type Library, and because I have Adobe Acrobat installed, I can edit/save just fine.
A coworker's machine is also using Adobe Acrobat 10.0 Type Library, he does NOT have Adobe Acrobat installed, and cannot edit/save.
My problem is this: I can't figure out how to tell VBA who does and does not have the Acrobat features installed and who doesn't. The GUID for the reference pulls 10.0 Type Library on both machines. I want VBA to check the users references and verify they do or do not have access to editing so I can lockout the features.
Is there a way to pull what version/access the user has from the library?

Answer 1

Perhaps the simplest way is to do something that fails in Reader, and detect the failure. Probably more reliable than trying to detect the installed product(s), which could also be BOTH Acrobat and Reader.
