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 think I finally found a FIX for this problem.

* (1) Go into: Menu\Preferences\Security (Enhanced) and un-cecking the following:

Enable Protected Mode at startup

Run in AppContainer

Enable Enhanced Security

Close settings window & PDF file would open IMMEDIATELY, but only one time.

********** NOTE: Step 1 alone DID NOT FIX because "Enable Enhanced Security" kept defaulting back to being checked, causing me to have to do this ALMOST every time I opened a PDF from my email and even from my local drive (See step "2" below). Otherwise, took 30+ seconds to open. Got VERY used to the shortcut (Ctrl+K, Alt+E, Enter!)... after finally having enough of this -

* (2) STEP 2: Since Step 1 above didn't seem to retain its settings due to "Enable Enhanced Security" re-enabling itself every time - I think I FINALLY found a fix that works.

Go into same menu: Menu\Preferences\Security (Enhanced)

Click "View Windows Trusted Sites"

Select "Internet" (should be defult), then drag the "Security Level for this zone" to "Medium" setting.

(mine defaulted to Medium-High)

Click "Apply" and close the settings window.

This fixed problem for me - Enable Enhanced Security still reverts back to being selected, but on the Medium setting, all PDF's now open as soon as I double-click - even when app is not already open.

@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

New Participant

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

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

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.

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

New Participant

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.

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.

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.

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.

Adobe Expert

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.
