This is an example on Windows 7 machine.
Copied VirtualServiceEnvironment.exe to VirtualServiceEnvironment2.exe.
Copied VirtualServiceEnvironment.exe to VirtualServiceEnvironment3.exe.
Copied VirtualServiceEnvironment.vmoptions to VirtualServiceEnvironment2.vmoptions.
Copied VirtualServiceEnvironment.vmoptions to VirtualServiceEnvironment3.vmoptions.
This for the VSE Services, but you can do this for the VSE Servers as well.
Edited the vmoptions for each vmoptions file. This file am using the default VSE port, but wanted the name to be other than the default of VSE.
Defining with VSE2 and a different unique port.
Defining with VSE3 and a different unique port.
Display on Server Console:
On Workstation, have a choice of the 3 VSEs to deploy to that are connected to this one Registry:
Note: If putting VSEs on different machines and going to the same Registry, use the same type of method as above for the VSE Name. Even though on different machines, if going to the same Registry, the names need to be unique. You would not have to specify different ports or log files if only one VSE on a machine.
