As of Quickbooks 2017 R5 and Quickbooks 2018 I am getting a licensing issue in XenDesktop
Citrix says its a 3rd party application issue
Quickbooks says they don't support Citrix
We have been using Quickbooks in XenDesktop for years just recently having issues.
what i have figured out so far
installing all additional packageds with the quickbooks 2018 installation doesn't affect the licensing service.
once quickbooks is installed
A netstat will show the following missing
Event viewer doesn't show any errors
citrix event viewer shows license not available when users attempt to login
if you use rdp instead of citrix your able to function fine.
