OSX Catalina with Acrobat PRO 2017, and networked scanner Epson
DS-520. I have installed the latest drivers and software for both
the Adobe software and the Scanner. When I start Acrobat and select
"Create PDF from Scanner", I get a pop up window with a choice of
scanners. I then select the EPSON DS-520 from the list and click
on SCAN. The SCAN button is then grey'ed out for a moment and
then its back to its original (blue) color.

Acrobat Pro just sits there doing nothing, no Epson Software appears
and Acrobat Pro shows no progress indicator. If I try to start
Create From Scanner again a dialogue appears saying "This operation
is not allowed, since scanning is in progress"

If I select QUIT Acrobat Pro I get the same dialogue box and end
up having to Force Quit Acrobat Pro.

Suggestions of how to resolve will be appreciated.
