Can't open digital signed PDF documents

Question

we can't open already digital singed pdf documents. Files that are not digitally signed do not experience problems.
The problem occurs with adobe reader and adobe acrobat.
the PDF reader opens but when loading the PDF it crashes.
I tried updating the program, windows updates, reparing the progam & reinstalling it.

Hi @Noppe Guy

Hope you are doing well and sorry to hear that.

Would you mind sharing the version of the Acrobat/Raeder you are using? To check the version, go to Help > About Acrobat and make sure you have the recent version 22.3.20281 (Mac) or 22.3.20282 (Win) go to Help > check for updates and reboot the computer.

Is this an issue with a particular PDF file or all the PDFs? Please try with a different PDF file and check. If the file is stored on a shared network/drive please download it to your computer locally and try again and check.

You may also try to turn off the protected mode for testing (Win Only) go to Edit > Preferences > Enhanced Security > Uncheck 'Enable protected mode at startup' and turn off the protected mode and uncheck Enhanced Security > Click OK and reboot the computer once.
Note: Please turn on the security after testing to avoid any security risk.

Let us know how it goes.

Regards

Amal
