Unified Service Desk app not loading updated custom assembly

Hi everyone

We are using USD 2.2 with CRM 2016 SP1 on-premise. We have a custom assembly which we deploy to USD using it's Customization File feature.

We have a situation in our staging environment (with multiple CRM backend, front-end servers and USD application being served to users from Citrix servers) whereby if a user logs in for the second time, USD is not able to load our custom assembly from the user's appdata profile (\[user name]\appdata\local\microsoft\usd) and comes up with a FileNotFound exception. When the user logs in for the first time or after the user cache has been cleared, USD app works fine, but not on subsequent logins.

I believe the issue has nothing to do with USD because I tried deleting/disabling caching on the browser, the USD app (USD->User Settings) and USD user account (USD->Options) to no avail.. Also, the problem does not occur in our dev or QA environments which have a single server configuration.

I am wondering if others have had this or similar issue with USD using user profile management with Citrix or other similar software.

Any help is greatly appreciated.

Regards

I'm guessing it is because of the Multiple servers, Is there any way for you to check by shutting down temporarily one of the servers and test?

One another thing I can think of is, Restarting the CRM Services in all the servers (specially if you have any cache server in middle).

QQ: Is it only happening for Customizations records? What if, If you a add a new hosted control, is it working as expected with out any changes?

Thanks for your response. My first question was not accurate as I did not explain things very well. So I have rephrased the question.

My answers your questions: I cannot shut down those servers, restarting the CRM services did not help, and adding a new hosted control did not help.

Thanks

Hello, have similar issue in online environment. I'm not using Citrix thought or other similar software.

Next steps resolve this issue:

1. Update attachment file in customization record

2. Update configuration version and ClientCacheVersionNumber

But that does not seem to be a good solution in other then on dev environment. Have you already managed to fix it?

I realize this is a stale thread, but I recently encountered the same issue and found a solution not mentioned here or elsewhere, so I thought I'd share.

The issue can be caused by permissions. In my case, the administrative user who updated the customization file was in a different business unit than the end users, who thus lost read access to it. Moving the admin user to the same BU as the end users resolved the problem for me, although I suspect that it could also have been resolved by mucking with security role configuration.
