Adobe Acrobat slow to open files.

[paul_6482]

I am having an issue since the latest windows update and Adobe updates where opening up multiple pdf's take an extremly long time. The problem appears to get worse if the file is large and the more pdf' you have open th slower it gets as well. If you close adobe acrobat down and reopen the first file opens quickly. I have 32 GB of RAM on a 13 generation i7 processor so processing power is not the issue. I have also tried disabling the security and enhanced security as well as disabling the show online storage when opening files. I have also disabled the modern Acrobat interface.

I have this issue on my Windows 10 machine, but also with other applications like Microsoft Word, which let's me think that it is an OS issue. As a workaround, I open Acrobat and use drag-and-drob.

Several users at our company are having the same issue, opening each file after the first one takes 30-60 seconds.  Some machines are Win10, others are Win11.  Adobe seems to be the only program with the issue, no problems with Word/etc.
Opening Acrobat then drag & drop does not speed it up at all, still takes forever to open.
Anybody else figure out a solution here?  I open PDF files all day long so this has really become quite a problem for us.

I opened up a ticket with Adobe support and spoke to a senior technician. They have assigned this issue as a bug ADC-4490483 and we are now waiting for them to fix the issue. The techncian did roll back the Adobe Acrobat to a previous version but that did not fix the problem which makes me think its a windows update that is causing the issue with the Adobe Acrobat application. The issue doesn't seem to be as bad if you are just using the Adobe Reader.

[derekm43837527]

Thank you @misty_5290 for reaching out to them and creating a ticket.  I tried rolling back to different versions as well (and updating to the newest version before that).  I agree with your theory that it's a Windows update conflict as all of our network PCs forced some Windows updates earlier last week when this issue started occurring for us.  Please keep us posted on any resolutions they come up with.  Thank you!

Have you had any updates from Adobe on bug number ADC-4490483?

Has there been any update on this? I have someone experiencing a similar problem and was wandering if any headway has been made on it on adobes end.

Hi,

Same problem in our environment. No matter if old win10 or new win11 install, but with these latest Adobe Reader versions opening pdf files are extremily slow. I have tried "everything", but nothing seems to work.

[derekm43837527]

The only "workaround" I've found so far, which only works about 50% of the time, is to uncheck the "Run in AppContainer" checkbox in Preferences.  Then the slowness opening files is more intermittent, again about 50/50 but it's better than it was.  Still waiting for a true fix.

Hm anyone have an idea if Adobe is taking it serius? Because I use PDf iles 100 times a day, so this isue is really getting on my nervs! Im contemplatting useing another PDF app!

[derekm43837527]

I'm in the same boat, driving me crazy!  I might as well get used to BlueBeam like several other people in our office use.

It is truly frustrating.  Class action lawsuit??? We pay a LOT of money for this product and my attorneys are beyond frustrated that they can't fix this issue. It has been months that this is a problem. 

[Jacob_5489]

This seems to still be an issue 

I have tried disabling the new acrobat and unchecking the run in app container and this issue still exists for our client. 

[timop9435524]

This is painful. It has a significant impact on our customer meetings, where hundreds of PDF documents are opened daily

[trelawney_4285]

@adobe is there an update on this issue?

I am seeing multiple clients with this issue. 

This occurs when the PC is on windows 24h2 and adobe version 24.005.20320

[timop9435524]

This occur also with older win10, not just win11 with 24h2

[derekm43837527]

I agree, I am on Win10 and I have several coworkers on both Win10 and Win11 and we all have the same issue.

[Rob23669396ksql]

same issue on 2 W11 computers

[roberth75067798]

Having similar issues in our environment on a few machines. Only true similarity is that they are fully updated W11 Pro machines with Acrobat Pro licensing. Files are slow to open whenever opening a file from explorer, but open quickly when opening from File>Open dialogue inside of Acrobat. Version rollbacks and re-installs have been unhelpful. It's odd because there are other machines in our environment running the same setup without issue and I can't find any clear difference between the machines that are and are not working.

Next step is likley to wipe out all adobe products, completely wipe them out in profile AppData and registry and reinstall, but hoping to avoid that if possible.

[timop9435524]

We ordered few new Adobe Standard licenses for totally brand new win11 workstations.  The problems started immediately on these machines as well. New installations behave exactly the same way as years-old Windows 10 workstations with fresh Adobe Reader installations and versions.

[default5xtwj2tnigix]

I performed a manual removal including files in AppData and registry. It didn't resolve the issue after re-installing.

[cafen_8707]

It is like it could be a compatibility issue with the latest updates k cup coffee pods. Have you tried clearing the cache or reinstalling Acrobat to see if that speeds things up.

[bradley_5558]

We are having the same issue, did this ever get resolved?

[scott_1150]

I am having this issue as well, everything is up to date and I did a clean install.  Anyone else have any suggestions?
