Sometimes the licenses are not properly written to the local licenses file on the machine.

For example, an upgrade or extension may be missing locally where it looks as though as it has been installed when viewing your SideFX account portal.

In the Houdini 21.0 License Administrator, you can select to synchronize the licenses to the machine.

In Houdini versions older than 21.0, you will have to import the .hlic file to synchronize the licenses. Or, you will need to contact the support team (support@sidefx.com) to have a licenses file sent to you for installation. Both of these methods will attempt to synchronize the licenses between the local machine and your SideFX account.
