Acrobat DC freezing or "not responding"

Tried something yesterday that seems to have helped ALOT.  Under Preferences & Adobe Online Services I unchecked Sync Settings\Sync preferences across devices and document services. The program is MUCH better now especially on large drawings.

I don't know if this is THE solution, but it's made Adobe Acrobat Standard DC much faster and better for us. I got suspicious that it was trying to reach out to the Internet or something. We seemed to have the biggest problems with large drawing files (we're architects).

Give it a try. Good luck.

I am having the same problem when trying to insert or merge files.  We are running Adobe Acrobat Pro DC version 2015.023.20056 on a Windows 7 network machine.  I've tried uninstalling and reinstalling.  I've run the repair installation tool and checked for updates (none).  I've turned off tabs and tried running Adobe with absolutely nothing else open...still the program either stops responding or I eventually get an "out of memory" error message before it shut itself down.  HELP.  The whole reason that my company got this subscription for me was so I could merge and manipulate pdf documents in an attempt to reduce paper usage.  Right now all I'm doing is spending my time trying to troubleshoot Adobe and attempting to find workarounds.  It's actually taking 3 times as long to work each file than it did using paper copies.

We're having the same issues on all of our computers (either Windows 7 or Windows 10) with Adobe Acrobat DC. It hangs "not responding" so much that the program is almost unusable. We've tried the suggestions and they don't make any difference.

I can't believe Adobe has this type of issues with a flagship product. Something is seriously wrong with DC.

What over PDF viewing and editing programs (not made by Adobe) would anyone suggest. We've tried Soda PDF 8 and we're too impressed. It was good for printing, but lacked the necessary zooming and annotation tools.

Thanks.

Like all of Adobe's recent products, I'm finding that Acrobat is extremely slow. I've tried all of the listed solutions, but to no avail. I'm on Windows 7. I'm getting really frustrated with the whole CC product. Everything seems to be so slow as to be unusable.

Ya, we are experiencing this today. with all the updates installed its still an issue.

i have a feeling that its down to some of the files the users are working on, as it definitely affects some files, and not others.

in our case, its when we go to use the measurement tool in adobe reader pro.

none of the fixes suggested resolve the issue. pretty shoddy by adobe in fairness.

happening on both win 7 and 8.1 machines.

Anything yet on fixing this issue?

I am a Windows 7 Enterprise Service Pack 1 64 bit computer using Acrobat Reader DC 15.020.20042.

Reader often locks up on me, usually when I go to print. 

It doesn't look like there has been any clear fix yet.  I do believe that the issue is part of the "Going out to the cloud" aspect of it.

Would signing out of the Adobe Online Service account fix it?

I had the same problem. Removing the tabbed interface seems to have fixed it.

I tried the 2 solutions, disabled the Protected Mode at startup and creating folder and keys in the regedit.

None of them worked for me.

The only solution that actually worked was deleting almost 4200 fonts I had installed on my PC.

Same problem and it wastes so much time..For every document I have to force quit and open it again or else it freezes. So annoying. Did an update as well still no fix of this issue. In fact, it got worse.

Any way to solve it?

THIS IS INSANE!

Has anyone at Adobe fixed tho issue yet?!?

I am on MacBook Pro, and all I see is talk about what to do on a PC and .exe files, none of which solve the issue on a Mac! I never had one issue, until a few weeks ago. I have CC, using Acrobat DC. It was fine. A few weeks ago it started not launching and not opening files. It is NOT the files. And every day now I work, next day it will not work, I have to uninstall, reinstall, and then get a day of work if I am lucky.

WHAT THE HECK HAPPENED, WHEN IT WAS FINE AND I MADE NO CHANGES TO ANYTHING?!? We all paid a lot of money for a program to have to troubleshoot every day. Any insight?
