I have a customer that I migrated to Win Server 2012 R2 as an RDS for their company's Quickbooks  (as well as a few other things)

The issue is that Quickbooks cannot see the TWAIN yet it has been installed. At least that what the installer says.

Now what's funny is that the administrator account could use it. none of the User accounts could. So naturally as a test I made everyone ADMINS.

But that didn't work.

Any ideas or something I may have missed?

Thanks!
