Acrobat Nag

I'd imagine this is happening through your web browser when you download pdfs. Just update your browser to not open .pdf files automatically and you shouldn't get this message, I think.

That setting should also be in Acrobat preferences...

Does that window come back if you choose Yes instead of No?

No, at least until change the default application for pdf files back to, say, Preview.

It has nothing to do with browsers, since this happens even when I simply open Acrobat from anywhere without any files.

Did you check the setting in Acrobat to make sure that's selected as the default for opening .pdf files?
OR, do you NOT want PDFs to open in Acrobat by default?

[Natobasso]

You have to tell your mac to open pdfs with something or it will ask you every time. If not Acrobat, then command + i on a pdf and choose Preview as your pdf opener of choice.

DeltaMac: I want (just like the OP, I think) Acrobat to remember that I don't want it to be the default pdf application. Telling OS X that I want preview works alright, just as Natobasso said.

The problem is that Acrobat keeps on asking to be the default (only when I open it manually of course, but that still happens from time to time).
