If you want to use Spotter Web, the main server MUST be running version 9.4 or later!
Spotter Web works only with the Enterprise Main Server.
OS limitations
If SpotterWeb is installed on client OS, there can be a maximum of 10 simultaneous connections:

For each SpotterWeb login, 3 connections are made: HTTP, SignalR for events and WebSocket for streaming. So for example Windows 10 Professional, only 3 clients can log in at the same time.
There are no similar limitations in server OS, so it is highly recommended to install SpotterWeb to Windows Server OS.
When installing SpotterWeb to client OS, the installer will give a warning about the OS/IIS limitations.
