UniViewer Console takes around 5 minutes to start on server where Remote Desktop Service is installed.
Release : 6.x
Component : DOLLAR UNIVERSE
Sub-Component: Univiewer Console
The problem occurs because of a limitation of the resources by session that is active on Terminal Services (https://docs.microsoft.com/en-gb/troubleshoot/windows-server/remote/fair-share-enabled-by-default-in-rds).
Inactivate that “Fair Share Scheduling” for CPU, Disk and Network, UniViewer Console starts in less than 30 seconds.
Workaround:
Use UniViewer WebConsole
