I am using Adobe Distiller to convert employee Pay advices to password protected PDF and emailing them out to employees in Dynamics GP and keep getting the following error: "Error registering Distiller window class. Another copy of Adobe Distiller may already been running. Error 1410 - Class already exists." It last worked correctly on July 6, 2023. If I respond "OK" it might convert another pay advice or two and then the error pops up again.
The errors started after the latest update by Adobe on July 11, 2023. Does that have anything to do with it? Have been using it for several years before this without issue.
I think you need to re-install Adobe Acrobat or update your Adobe Acrobat version!
With Win 11 you better get the latest Adobe Acrobat Pro which includes Distiller.
