Flash and Air Updates Remove Scanner From Acrobat and Photoshop Elements Menu

Hello,

The latest Flash and Air online updates remove my Epson WF-3620 from the scanner drop down lists in Acrobat 11.0.16 and Photoshop Elements 11.0 in Windows 10 x64 on a Toshiba Satellite P50-B. The WF-3620 was the last / most recently used scanner. System restore does not bring back the WF-3620 selection.

What file does Acrobat and Photoshop Elements use to get the scanner list?

Thank You.
