Question details

- Product
- Adobe Acrobat
- Device & OS
- Windows and macOS
- Scenario
- Attempting to scan a physical document to PDF when the application suddenly becomes unresponsive.

Force Close Adobe Acrobat on Windows using Task Manager
Use the Windows Task Manager to forcefully end the Acrobat process when it stops responding during a scan.
When a program like Adobe Acrobat completely freezes, the standard close buttons will not work. The Windows Task Manager allows you to bypass the unresponsive interface and terminate the background process directly.
Press Ctrl + Shift + Esc on your keyboard simultaneously, or right-click the Windows taskbar and select Task Manager from the context menu.
In the Processes tab, scroll through the list of running Apps to find Adobe Acrobat.
Click on Adobe Acrobat to highlight it, then click the 'End task' button located at the bottom right corner or top menu of the Task Manager window.
Force Quit Adobe Acrobat on macOS
Use the macOS Force Quit Applications menu to close Acrobat if you are using an Apple computer.

Frequently Asked Questions
Why does Adobe Acrobat get stuck while scanning a document?
This typically occurs due to a communication breakdown between your scanner's driver and the software, a loose connection cable, or a temporary memory overload in your operating system.
Will I lose my scanned pages if I force quit the application?
Yes. Any pages that were scanned but not saved as a finalized PDF file before the application became unresponsive will unfortunately be lost and need to be rescanned.
How can I prevent my PDF software from freezing during future scans?
Ensure your scanner drivers are fully up to date, check the physical USB or network connections, and avoid running multiple resource-heavy background applications while scanning large batches of documents.
