Acrobat Pro DC will not open any PDFs

I suddenly had the same issue of being able to open the application, but was not able to open any PDFs. No error messages, etc. I did a live chat with Adobe support and they told me to open Acrobat - go under the Window menu - Click on "Zoom". Once I did that my initial start window opened with all my recent documents that had been opened and I was able to open other PDFs. All is good now.

So I was having this problem as well.  (I am on OSX High Sierra 10.13.3).  It has been an ongoing issue for a few weeks now, double-click a PDF and Acrobat opens, but there is no PDF visible.  It has been driving me crazy because it is annoying to only be able to see the PDF using Preview in OSX.

I work primarily in VFX and there are a couple of my applications that have an issue when I switch between having an external monitor and not having one (I am on a laptop).  The window location does not update when I unplug the external monitor, so if I have a non-modal window on the second monitor, I can't get to it if I unplug the monitor.  Most other apps automatically move all the windows so that they are only on active monitors.

Well, I was sitting here trying desperately to open a PDF, and it occurred to me that I may have had the last PDF I used on my external monitor, which was the case.  I plugged in the external monitor and there was the PDF.  I then unplugged the external monitor and the PDF did not move.  I then used a trick that works sometimes on my other apps.  In the Adobe DC menu, go to Window and then pick Cascade or one of the Tile options. This will rearrange windows on the current monitor to Cascade or tile them.  This brought my PDF to my laptop screen and now I can view PDF's again.

Again, this worked for me, it may not work for you if you don't use external monitors.

EDIT:  I did also try uninstalling and reinstalling Acrobat DC from the CC menu.  It kept all the settings between installations apparently

So I found a solution...not "THE" solution. But I have been working with Adobe on this. We tried a reinstall...didn't work. We tried the cleaner... didn't work. We event did a complete Cloud reinstall...didn't work. So they sent me a link to download Acrobat from 2015. This works. I just have to get a serial number so I can use it past 15 days. Not ideal but at least I can view pdfs again.

So it's been like 8 months and Adobe doesn't know how to fix their own software? Do they just not care about the Acrobat program? Maybe we should take this to social media to get a better response.

I have the same issue.  Has anyone found a solution?

I have the same issue. I'm running Mac OS Sierra 10.13.4 on a new MacBook Pro 15" Acrobat Pro DC opens but files doesn't open.

We have had the same problem with Acrobat DC. We have a Mac OS X and some email pdf file attachments open ok, but some attachments open as 'scrambled' letters and figures. We have found that by right clicking on the e-mail pdf attachment and opting for 'download' (left click), then clicking on the download icon (top right of screen) to open the downloads list, then right clicking on the downloaded attachment, then choosing 'Open' from the menu (left click), the attachment opens. This seems to work both for texts and images.

I have the same question

I moved your question to the Acrobat General Troubleshooting forum, first of all.

What happens when you try to open a PDF file? Is there an error message of some kind?

Also, are you able to open the application on its own, without trying to open a file?
