Not able to sign a PDF document

Question

Greetings everyone,

I am unable to sign a PDF document. I continue to receive the 105 error message.

Thus far I turned off the settings under Security (Enhanced), checked for updates, Optimized the file. No luck. Any support you can provide is greatly appreciated. Many thanks.

Hi @Tiff TCCS ,

See if this solution resolves the issue:

I'd recommend also to try two things if the solution above doesn't resolve your issue:

Force a manual update of the operating system and also of Adobe Acrobat (just to rule if you're mising any optional updates)
repair the installation (if you haven't done so yet)
