The first and most important thing to note with network licenses is that the license server is a single computer. Once activated that one machine can serve multiple clients.

That computer doesn't need to be a Server in the typical sense of the term, but it should definitely be a computer on the same network as the clients and it should preferably be a computer that can be left on so that clients are always able to access it. In that respect, putting the license server on a server computer is usually preferable.

The license server computer does not need to be able to run arivis Pro/Vision4D, it just needs to be able to run the license distribution tool. The License Server can be installed on either Windows or Linux machines.

Virtual machines should be avoided as changes to the VM can irreversibly invalidate the license. Support related to licensing invalidation due to VM changes may be chargeable.
