For customers who are on v2021 these paperless office type error messages continue to appear. It is most noticeable/problematic for any user where they are not a local administrator on their computer as that requires we pull in IT resources.
I suggest that one change could be to the test converter functionality which is accessed through pl_advancedoptions_ui
I have seen in many ( all ) cases where I am doing hand-to-hand combat with this Amyunit/Paperless driver that the driver will test fine ( test converter ) but the customer will continue to receive errors ( generally -30 or -40 ).
Super big time waster chasing these errors
