I'm aware that this isn't supported (https://answers.laserfiche.com/questions/46687/Scanning-over-Citrix) but I'm hoping someone might have an idea about what is going on.  My client is using Xenapps 6.5 trying to scan into Laserfiche using a twain driver.  They have a couple Canon scanners as well as a Fujitsu.  The one we have been diagnosing is a Canon DR3010C but all the scanners do the same thing.  The Laserfiche client is version 9.1.1.  When running Laserfiche outside of Xenapps, there are no issues.  The IT staff has installed something called "Remote Scan" which appears to be a Dell product in an effort to get this working on Xenapps.

Here's what happens: The scan starts off fine and pulls a page through the scanner.  Once it is done, the green "scan documents" button comes back up, the scan interface shows an hourglass everywhere on the scan interface and there is NO image displayed in the scan window.  It is like it is waiting for a prompt but there are no prompts anywhere on the desktop.  I can close the scan interface and everything shuts down properly.  I can even click "scan documents" again and it will run another page through the scanner.

What I think is happening is that there is some sort of communication issue with the Laserfiche Scanning Temporary folder (C:\Users\<username>\AppData\Local\Temp\Laserfiche Scanning).  They are currently set up using Roaming profiles that get regenerated when the user logs into Citrix.  I had them generate a local temp path on the server for the user having issues and the scan interface generated a "cached thumbnails" folders when we started a scan.  However, it was not placing any images directly into the "Laserfiche Scanning" folder like it does when scanning locally.  

So, am I on the right track here?  Is there something we aren't configuring properly?  Is there a way to utilize the roaming profile instead of the local profile?
