Question

Adobe Acrobat Reader not opening

For the last month and a half we have had an issue with Adobe reader not opening. Users report that PDF files and Adobe reader aren’t opening.

 

I checked and multiple processes are running in task manager. I’ve ended those tasks and go to reopen Adobe but it does not launch. Two Adobe processes are running in task manager and at 0% or 0.1% CPU and 0MB or 0.1MB and do not change. There are no logs generated in Event Viewer → Windows Logs → Application or System when Adobe is opened or when the processes are ended.

 

We’ve tried repairing and modifying Adobe but that doesn’t work. Uninstalling and reinstalling Adobe, only works for a day or so and then the issue comes back. Tried uninstalling with Revo uninstaller too but the issue still comes back. Same thing with restarting, works for a couple days then we’re back to Adobe not opening. We have users on the latest version - 26.002.21931

 

Any ideas on how to resolve?

    Hi @Festive_intelligence6b8c

    I hope you are doing well, and thanks for the detailed report and for sharing everything you have already tried. I’m sorry for the trouble this is causing your users.

    To help us look into this, could you please share:

    1. Which Windows version are the affected devices running, and how is Adobe Reader installed on them (manually or through a deployment tool such as SCCM or Intune)?

    2. What are the names of the two Adobe processes you see in Task Manager? A screenshot of the Details tab would help.

    3. Is every user affected, or only some? Do you notice anything that happens just before it stops working, for example, a Windows update, a restart, signing in, or opening a particular PDF?

    4. Does the issue happen when you open Reader directly as well as when you double-click a PDF? A small video recording of the steps you are taking and the issue as it occurs would be very helpful.

    Note: Please make sure any screenshot does not show personal or sensitive information.

    Once we have these details, we can look into it further and share more troubleshooting steps

    Regards,
    Amal
