Acrobat Reader MUI interface freezes after manual signature validation

Question

Acrobat Reader MUI (22.003.20282) completely freezes in this scenario:
* deselect from the signature validation preferences "Verify signatures when the document is opened";
* open a signed document and validate the signature(s) (tested using "Validate All".
The only way is to close it from the Task Manager.

Moreover, signature validation is usually extremely slow compared to other validators.

Hi @Jhacks

Hope you are doing well and sorry to hear that

Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check.

Please try to repair the installation from the help menu (Win Only) and see if that works.

Please try to reset the Acrobat preferences as described here https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-default/td-p/4792082

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

Regards

Amal
