I am getting an error, everytime I open a PDF or download one online. The file is still accessible and viewable but I keep getting an annoying error that won't go away despite deleting old adobe and reinstalling, also ive updated the security property settings and no fix.

Please help with this as it has been happening the past couple of days and it is very annoying, let me know if I can disable notifcaitons entirely

I face the same issue specifically when opening the PDF from the new outlook

Hi @gravytrain31 @Mohammed26254782itdo, 

Sorry for the delayed response and troubled experience. This known issue was fixed in the September product update release. Ensure your application is updated with the latest update patch. To check for pending updates, launch Acrobat > Help > Check for Updates. 

If you’re still encountering this issue, I encourage you to share any additional details or steps that led to the problem. This will assist us in diagnosing and fixing the issue more effectively.

Thank you for your patience and understanding as we work to make things right.

I checked for updates and there are none. I'm still getting the below error when opening from Outlook New.  I'm using Adobe Acrobat Pro, verson 2024.003.20180  64bit 

[fernando_0254]

Same issue. Adobe Acrobat Pro version 2024.003.20180. 

Still getting the error.

Downloading the file and opening it from a local location is working.

Note: tested using New Outlook. Pending testing with "Classic version".

I'm getting the same error with the latest update. It happens with Classic Outlook as well.

Hello,

Please advise.

Hi,

it is still happening even after the update. The issue is causing only while opening any PDF attachment from the outlook app.

[Nikodem Korzeniewski]

Hello,

Any idea on a fix or workaround?

Hi @Mohammed26254782itdo @Nikodem Korzeniewski @agentis,

Hope you are doing well. Sorry for the trouble. 

We have forwarded the log ID to the dev team for further investigation.

While the team looks into it, here are two suggestions you might want to try:

1. Go to Acrobat-> Preferences-> Security (Enhanced)-> uncheck the checkbox "Run in AppContainer"-> Restart Acrobat.

2. If the above doesn't work, try running the app in Compatibility Mode. To do so, right-click the app icon-> properties-> compatibility-> check the box saying "Run the app in Compatibility mode for"-> select Windows 8 in the dropdown-> Apply-> OK.

Let us know if this works.

Hello @S. S 

I think you cracked the code.

The first suggestion looks to have resolved the issue.

Many thanks.

Kind regards,

Nikodem

Hi @Nikodem Korzeniewski,

Thanks for letting me know that it worked.

This also worked for me, suggestion 1!

[ScraggyScale]

Issue exist also in latest Adobe Acrobat Classic releases (i.e. 24.001.30225 Planned update, Dec 10, 2024).

Only way to fix is to completely disable Protected View. Just disable "AppContainer" doesn't work at time of this post.

[authentic_doer8809]

Hi, Option 1 did not work for myself. Option 2 did. Thank you. 

[Jean23190799mimp]

Did not work for me either.

[hloniphani_1128]

Worked for me the 2nd suggestion.

[adneci66]

2. If the above doesn't work, try running the app in Compatibility Mode. To do so, right-click the app icon-> properties-> compatibility-> check the box saying "Run the app in Compatibility mode for"-> select Windows 8 in the dropdown-> Apply-> OK......this worked for me

[Gina_223]

@S. Sthank you for the suggestions and agree with @Nikodem....you cracked the code!  Still had errors after applying the first suggestion but the second resolved the issue.  

Many thanks!

Thank you!! So glad I found this post. Frustration is now over. Unclicked Run in App Container and the error has gone away.

[Christie27885068idob]

Since the updated in November clearly did not fix this issue, do you have a timeframe for when it may be fixed? Are developers at least acknowledging the November patch did not work? 

[default08ikzhbrrv3s · Accepted solution]

I found this on another Adobe Community Post and it worked for me today 3/28/25 ...

There were some posts about this issue from over 5 years ago, and the solution offered then (updated slightly) fixed it for me. It's much easier that uninstalling / reinstalling the app:

1. Find your Adobe Acrobat program.

2. Right Click --> Properties.

3. Select Compatability tab.

4. Click on Run Compatability Troubleshooter.

5. Select Try Recommended Settings.

That's it. Hope it works for you.

This solution worked for me, thanks!  5/22/2025

[ski_9124]

7/23/2025 and this solution resolved my issue for the problem as well after trying multiple other steps suggested by Adobe support.

My advice is try this one first as it requires nochanges to your preferences or security settings. In my case, and many others it seems, its simply a compatabilty change that is needed.
