Frequently Asked Questions
Why does Acrobat XI close without showing an error code?
Silent crashes in Acrobat XI, particularly in version 11.0.09, are frequently caused by unhandled software exceptions related to PDF security and decryption protocols. Updating to the 11.0.23 patch resolves most of these documented bugs.
How can I tell what version of Adobe Acrobat I am running?
Open Adobe Acrobat, click on the 'Help' menu at the top of the window, and select 'About Adobe Acrobat'. A dialog box will appear displaying your exact current version number.
Is Adobe Acrobat XI still officially supported?
No, Adobe officially ended support for Acrobat XI on October 15, 2017. Because it no longer receives security updates or bug fixes, users experiencing persistent crashes are encouraged to use modern alternatives like WPS Office.
Can I remove the password from a PDF to stop the crashing?
If you are able to open the document using another PDF reader, you can remove the password protection (provided you have the permissions password) and save it as an unprotected PDF. This often allows older software to open the file without crashing.
