In addition to registering Arnold in the global ProductInformation.pit file used by all Autodesk products, AdskLicensingInstHelper also registers Arnold with the Autodesk licensing service (that’s for single-user licensing).

For example, let’s suppose you want to render Maya scene files.
You need to install Maya and MtoA on each render node.
You don’t need Maya licenses for batch rendering, and you don’t need Maya licenses to install Maya on render nodes.
You need Arnold licenses, which are a separate purchase. MtoA is free and unlicensed. Arnold, however, does require a license to render without the watermark. You need one Arnold license for each render node (for you CINEMA 4D users, a TeamRender client is an Arnold render node and requires its own license).
