You can optimize V-Ray for Unreal installation in this step by manually setting the location folder where V-Ray for supported Unreal versions will be installed. This page is accessible if nothing in Host app version page is selected.
Install V-Ray for Unreal Engine 4.## – Enabled the installation of V-Ray for Unreal for the specified Unreal Engine version.
Unreal Engine 4.## plugins location – Allows you to specify an installation location for V-Ray for Unreal. A path to Unreal's Plugins folder must be specified e.g C:\Program Files\Epic Games\UE_4.26\Engine\Plugins
Licensing
In this step, you can specify whether the V-Ray License Server will run locally or on another machine.
If you select the option Remote, you will have to fill in the IP address of your V-Ray license server in the field Primary License Server. Please, leave the port 30304 unchanged. An Alternate License Server is used when the primary one does not respond.

Then it automatically uninstalls all old versions.
