Excel VBA Adobe Acrobat Automation Error - The remote procedure call failed.

  • Greetings:


    We've been leveraging the code below for several years to automate the production and assembly of a collection of PDFs, and all has gone well as we've upgraded from Acrobat 10 Pro to 11 Pro to DC Pro. However, as my staff has upgraded recently to Acrobat Pro 2020 and Office 365 we've encountered an issue.


    The creation of individual PDFs still occurs without fail, but the code now breaks at the point noted below when it begins to assemble the "packet" of multiple PDFs.


    Code snippet here:



    We cannot figure out why the upgrade to Acrobat Pro 2020 would cause the code to fail. Anyone have any thoughts?


    Much appreciated.
