Active Indie and Education subscriptions are issued upgrades to the account automatically.

If you are using SideFX as your license server, there is no need to install the upgrades. Just download Houdini and launch.

If you have installed licenses locally to your computer, you must install the upgrades to the existing installed licenses.
It is not enough that you only install the latest version of Houdini; the licenses themselves need to also be upgraded.

Commercial customers are entitled to upgrades to those licenses on an active annual support plan (AUP) or rental.
If you have Commercial licenses and do not have upgrades, please contact your SideFX account manager.

Ensure that you are running at least a license server (sesinetd) at version 20.0 to use 20.5 licenses.
