Re: Undo and Redo Greyed Out?

Hi there

Hope you are doing well and sorry for the trouble. As described you are unable to undo and redo the changes to the PDF file.

I have tried to reproduce the issue on my end using Acrobat Pro DC version 21.05.20060  on Win 10 and its working fine.

Please try to repair the installation from the help menu and reboot the computer once and see if that works. Go to Help > Repair Installation.

If it still doesn't work, please try to reset the acrobat preferences as described here - https://community.adobe.com/t5/acrobat/how-to-reset-acrobat-preference-settings-to-default/td-p/4792... and check.

You may also try to create a new test user profile with full admin rights in Windows and try using the application there and check.

Regards

Amal
