We have a customer that was having trouble installing a scanner on a new machine using the ISIS protocol instead of twain.
I looked at it with them. We visited the scanner manufactures site and ensured we were downloading a driver that included ISIS as a protocol along with TWAIN and WIA. It is a one package does it all deal, they are not separate downloads.
As we went through the installation wizard we made sure there was no where to click where we needed to enable ISIS specifically. It seemed we had successfully installed an ISIS driver.
Windows Driver details do not specify these protocols though, so hard to tell for sure.
However in Quickfields when choosing scan connect no ISIS drivers are detected, when choosing TWAIN the driver is detected. The same one that should include all the protocols.
Is there an extra step to enabling an ISIS driver in Windows? How do you even verify that you have this type of driver installed?
