Some of staff have been getting upgraded on Windows 10 PCs. When I installed the DocuWare Printer (6.6), the printer does not show up as an option in the print window. There was a zipped file that I kept as a fix when this issue first occurred late last year. Today I used it to add the two missing dll files and the DocuWare Printer still does not get added as a print option when the user opens email attachments. I tested my own PC (I don't use the DocuWare Printer normally) and it installed with no problem. My version is Windows 10 Pro Version 10.0.17134 Build 17134
