Adobe won't open PDF until I end the task in task manager

Hi,

Has anyone else experienced an issue opening PDFs in the last few days? Everything worked fine until 2-3 days ago but now I open a PDF in Adobe without issue, then when I close the program and try to open another PDF, Adobe won't open. Nothing happens. I have to end the task in task manager and then the PDF will open no problem... but I have to end the task each time.

If I leave a PDF file open, it will open another PDF without issue. It's only when the program is closed completely and I try to open another PDF that I have this problem. It's easy enough to work around but annoying nonetheless... any thoughts on how to fix?

I've tried restarting my computer, uninstalling and reinstalling Adobe, didn't fix it.

Running Windows 11 Professional on a laptop.

Bonjour,

Je sais que le post est vieux mais pour ceux qui rencontre le problème. J'ai contacter le support Adobe.

Hi @Joshua27140953w9bi @kunal_2157

Would you mind sharing the required information as described in the previous reply, so we can raise it to the engineering team to further look into this and isolate the issue for the fix.

A short video of what you have described, if possible.
Diagnostic logs

To collect the logs: Download and run the Diagnostics Utility from: https://helpx.adobe.com/acrobat/kb/acrobat-diagnostics.html

Click on Start Diagnostics. Ensure advanced logging is checked.
Launch Acrobat, reproduce the issue with your file.
Once done, click Stop Monitoring.
Copy the Log ID and share it with us.

We would also need these logs: https://helpx.adobe.com/acrobat/kb/collect-logs-crash-freeze.html

Upload logs to any Cloud Drive(One Drive, Google Drive, Dropbox, etc)

I’ve been experiencing an issue very similar to what others have described, where Adobe Acrobat does not appear to launch.

When users open the application, nothing happens on screen. However, if you check Task Manager, multiple background processes are created. Because there is no visible response, users tend to click the application multiple times, which results in many instances of Acrobat running in the background.

My assumption (speculation) is that the application begins to launch but fails partway through the process. As a result:

The GUI never appears
No error message is displayed
Additional launch attempts create more background processes

As a temporary workaround, I’ve been:

Opening Task Manager
Ending all Acrobat-related processes
Relaunching the application successfully

However, this issue occurs multiple times per day.

I also attempted to automate a fix using a PowerShell script that forcefully terminates all Acrobat-related processes at user logon. This was deployed across multiple machines. Initially, it appeared to resolve the issue, but the problem returned later the same day.

# Kill existing stuck Acrobat processes

Get-Process AcroRd32, Acrobat -ErrorAction SilentlyContinue | Stop-Process -Force

# Do NOT relaunch — user will open it manually

exit 0

Environment:

Windows 11 Pro (latest version at time of writing)
Issue affecting multiple machines

At this point, I suspect this may be an issue with the application itself rather than user environment or configuration.

If anyone has experienced this or found a more permanent fix, I’d really appreciate any suggestions.

We’ve had the same issue for the past 2.5 weeks, looked up on the Adobe Community but no solid fixes. Is there a permanent solution to this problem? we have removed/cleaned up Adobe Pro multiple times but issue still exists. Adobe is now becoming a hassle for users since they cannot open documents swiftly.

These solutions on the community and from adobe - DO NOT WORK!😕

Hi kunal_2157,

I raised this issue with Adobe last week, and I understand it is still under investigation. In the meantime, I continue to experience the same problem consistently.

One potential troubleshooting step I’d like to suggest is switching back to the previous version of Acrobat using the in-app menu option (“Disable New Acrobat” / revert to classic view). It would be useful to confirm whether the issue persists in the older version, as this may help isolate whether the problem is related specifically to the newer interface.

As a temporary workaround, I have been using alternative software, which is currently meeting our requirements. However, I am keen to understand if there are any updates on the root cause and whether a fix is planned.

This also started happening to me yesterday (8/21/25) - the compatability solution did not work. I'm running Acrobat Reader on Windows 10 Pro. I have 25.001.20630. Disabling protected mode did not work. Unfortunately I don't have the capability to make a full user profile.

Hello @allison_6257

I hope you are doing well, and we apologize for the delayed response and the trouble.

Please reboot the machine once and try a clean installation using the Acrobat Cleaner tool. Then, restart the machine and install Acrobat Reader from the direct link. If you're unable to do the uninstallation and create a new user profile with full admin rights due to IT restrictions, I recommend reaching out to your system administrator/IT team and requesting they perform the steps.

If the issue persists with the new user profile, please collect the logs from the affected machine and share them with us. To collect the logs, download and run the Log Collector tool. Make sure to select all log options and attempt to reproduce the issue. After that, close the Log Collector tool; it will generate the logs along with a log ID. Please share this log ID with us for further investigation.

Thanks,

Anand Sri.

Exactly the same issue has been faced for the last 3-4 days. Uninstalled and installed Adobe & rebooted pc multiple times. Even after I close all PDF files, it remains open, and to see that, we have to go to Task Manager. Task bar does not show PDF open file but in Task Manager we see many are open there to end the task

Hello @Whispering_sincerity7853

I hope you are doing well, and we are sorry for the trouble you had.

Could you please share more details about the issue? Are you on a Mac or Windows machine, and what is the version? What is the current version of Acrobat installed? To identify, please see this article. Please ensure you have the latest version of Acrobat installed on the machine: 25.001.20630 Planned update, Aug 18, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and try again.

Disable Protected Mode (for testing purposes): Go to Menu > Preferences > Security (Enhanced), Uncheck Enable Protected Mode at startup. Click OK and restart Acrobat.
⚠️ Note: If this resolves the issue, re-enable it after troubleshooting to keep your system secure.

For testing purposes, please create a test user profile with full admin rights, install Acrobat, and check. If the issue continues, please provide the following information: the current version of the operating system on your device and the logs from the affected machine. To collect the logs, download and run the Log Collector tool. Make sure to select all log options and attempt to reproduce the issue. After that, close the Log Collector tool; it will generate the logs along with a log ID. Please share this log ID with us for further investigation.

Same problem here. It's pretty random. Will open once then not at all. Then, I'm ending the "Adobe Reader and Acrobat Manager" task to get it to allow me to open another file. Then, it will go a few times and then not allow me to open again.

Frustrating. But, I have a workaround for now.
