Question details
The user is trying to uninstall or reinstall Adobe Acrobat but is blocked by a system error stating the application is open in multiple locations.
- Product
- Adobe Acrobat / Acrobat Reader
- Device & OS
- not provided
- Scenario
- Uninstalling or reinstalling Adobe Acrobat from the system.
- Observed behavior
- The uninstallation process fails and displays an error message indicating that running processes must be closed before continuing.
Save all your ongoing work in other applications, as you may need to forcefully close background services or restart your computer entirely to clear the locked processes.
Force Close Adobe Processes Manually
Use your system's activity monitor to forcefully terminate all hidden Adobe background processes, such as updaters or background assistants, which prevent uninstallation.
Even when all visible Adobe windows are closed, background services like Adobe Updater or Acrobat Assistant might still be running. You need to manually terminate these processes before the uninstaller can proceed.
Right-click the taskbar and select 'Task Manager', or press Ctrl + Shift + Esc on your keyboard.
In the 'Processes' tab, look for any process starting with 'Adobe', 'Acrobat', or 'Reader'. Select each one and click 'End task' at the bottom right.
Press Cmd + Space to open Spotlight Search, type 'Activity Monitor', and press Return.
Search for 'Adobe' or 'Acrobat' in the search bar. Select the processes, click the 'X' button at the top, and choose 'Force Quit'.
Once all related processes are completely closed, go to your Control Panel or Applications folder and run the Adobe uninstaller again.
Restart Your Computer Before Uninstalling
A clean system restart clears temporary locked files and prevents standard applications from reopening immediately, allowing the uninstaller to run successfully.
Looking for a Lighter PDF Editor? Try WPS Office
If background processes and heavy resource usage are making your current PDF software difficult to manage, consider switching to WPS Office. It provides a lightweight, fully-featured PDF editor alongside Word, Excel, and PowerPoint alternatives, running smoothly without locking up your system.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button.
- 2. Install WPS Office: Run the lightweight setup file and follow the on-screen prompts to complete the installation in seconds.
- 3. Set as Default PDF Viewer: Right-click any PDF file, select 'Open with', choose WPS Office, and check 'Always use this app to open .pdf files'.
Frequently Asked Questions
Why does Adobe Acrobat keep running in the background after I close it?
Adobe software often utilizes background services for automatic updates, cloud syncing, and quick-launch assistants. These services remain active in the system tray or background processes to speed up loading times but can prevent uninstallation.
What should I do if the Task Manager says access is denied when ending a process?
If you receive an 'Access Denied' error, try opening Task Manager as an administrator. Alternatively, simply restarting your computer is the best way to clear locked system permissions safely.
Can I use a third-party uninstaller tool to fix this?
Yes. If standard removal fails, you can use the official Adobe Acrobat Cleaner Tool or a reputable third-party software uninstaller to forcefully terminate related processes and wipe out residual registry files.
How do I stop Adobe from automatically launching on startup?
On Windows, open Task Manager, navigate to the 'Startup' tab, locate the Adobe Updater or Acrobat entries, right-click, and select 'Disable'. On macOS, go to System Preferences > Users & Groups > Login Items, and remove Adobe from the list.
