Upgrades are provided to commercial licenses which have an active support contract (AUP).

It is not enough that you install the latest Houdini release. You need to apply the upgrades to your installed licenses.
You may run older versions of Houdini with the latest released license.

Using the License Administrator is the easiest way to upgrade licenses:

1. Download and install the latest Production Build or the latest Daily Build.

2. Launch the License Administrator on the machine you wish to upgrade.

3. Select File->Login to log into your SideFX licensing portal.

4. Select File->Install Licenses to view your license entitlements.

5. Press the Install button. This will apply the upgrades to the current licenses.

If you are having problems logging into your account through the License Administrator, please see the section I can't log into the License Administrator.
