I have a customer that has Epson DS 530 Scanners that they have used for scanning in DW 5.1b.  We upgraded them to DW 6.11 and the DW Desktop scanner app will not see the Epson Twain driver.  Other apps on the PC still see the Twain driver, just not the Desktop scan app.  The customer uninstalled the driver, rebooted the PC and reinstalled the Twain driver.  They have also uninstalled DW Desktop and reinstalled.  The scanner is still not showing up.

Anyone else had this issue with an Epson DS 530?
