Hi

Arr you opening the pdf in a browser
If so
Check this thread

And ensure that

  • Browser: Internet Explorer - Disabled protected mode within Internet Explorer Security Options
  • .NET Package: Up to date
  • uninstall and install UIPath again

And if you are using adobe then

As per documentation, the Adobe DC is not fully supported. It is advised to use an older version to get it to work properly for now. It will be improved in the future, of course :slight_smile:

Check this thread for further updates

Hope this would help you resolve this

Thanks!

I am using Acrobat Reader DC 21.007 version, UiPath Studio 2021.4.4 version and updated the UIAutomation Activities to the latest one as well. Still unable to record.
Note: This is happening only with the pdf’s which have a message(Signed and all signatures are valid, but with unsigned changes after the last signature.)
