Using Mac, OS X Mavericks (but the problem has persisted though three versions of OS X and has continued in Mavericks: It is NOT new in Mavericks).
If Acrobat Pro is already running, double-clicking a file displays an error: The document "xxx.pdf" could not be opened. Acrobat cannot open files in the "Adobe PDF document" format. Clearly, Acrobat CAN open these documents. If Acrobat Pro is not already running, double-click xxx.pdf opens in Acrobat just fine. This has been the cast through three operating systems, and two versions of Acrobat pro. What is up?
This happens with all PDF files, which all open correctly if Acrobat is not currently running. THe files are not invalid, the file association in OS X is valid, everything works FINE if Acrobat is not already running with a PDF file open when I double-click a PDF file. Since there are a zillion questions about this online, I have to believe it's a continuing problem. It has been a problem for me for several years.
Any thoughts? -- Ken
When you note "Three Versions of OS X" - were these in-place upgrades? In-place upgrades are notoriously flaky and clean installations are recommended. (You will not see any documentation from either Microsoft or Apple to this, but it is pretty well known fact.)
Have you tried creating another user account and testing?
Nope. Clean OS installs.
Three different computers, too. Should have mentioned that. It has always worked this way for me: If a document is currently open in Acrobat Pro on the Mac, I cannot double-click another PDF document and load it for editing. Is this really not happening to everyone? It has been consistent across computers, versions of Mac OS X, and versions of Acrobat Pro for years. Thanks. -- Ken
I just double checked and I opened Acrobat XI first then did ⌘-H to hide Acrobat. Then I located a PDF and Double Clicked.
I've never had your issue since OSX.2.8 up to OSX.9.0 (Mavericks). So it’s a problem with your set up or some type of Utilitity , Plugin or extension is interfering.
I don't know how to tell you how to troubleshoot.
Try the Following:
Restart with shift key down
Then open acrobat.
Then Hide Acrobat and double click on a PDF.
If you don't have the problem you have a a Startup Item.
Will investigate other startup items, but the important part is a PDF has to be open in Acrobat Pro to cause the failure. If Acrobat is open and hidden, there's no problem.
And now, it's not reproducible, 'cause I just tried it and it worked fine. (Quit Acrobat. Double-clicked a PDF to load it, and then double-clicked a second one. They both loaded fine.) But it happens often, and clearly, I'm not the only one (search on the exact words of the error message, and you'll find a lot of hits).
But I'll try starting up with no other apps loaded, and see what happens.
