Aranda Virtual Support (AVS) uses Aranda’s common licensing service to authorize users to access the AVS website and control the licenses purchased, among other operations. This is a Windows service that is usually created automatically by the product installer. Once the user uploads their purchased licenses from the website, the common licensing service must remain on the same machine, otherwise the uploaded licenses will be lost. If your application server is located on a virtual machine, it is recommended that you install the Common Licensing Service on a physical machine, because when you restart virtual machines, there is a high probability that the hardware brand will change and the service will incorrectly assume that it was moved. Check with the vendor for details on server deployment.
