Why can't I use my licenses after upgrading?

If you had licenses installed to your machine, check that you are not looking to sidefx.com as the license server.

Login-based licensing is a new feature introduced in Houdini 18.5. It allows you to use sidefx.com as the license server but this will only work if you return the currently installed licenses from your machine back to your SideFX licensing portal.

To set Houdini to look to your machine for licenses:

  1. Open the Houdini License Administrator(hkey)
  2. Select File -> Change License Server.
  3. Add your machine name from the Found Server(s) list by pressing the + button.

In this example, only the SideFX license server will be used for licensing.

Choose Local Server

Add your machine (Local Server) to the license server search list.
In this example, the SideFX license server will be used first. If no licenses can be found, the Local Server will be used.

Search Server List Default

Change the order of the license server search list.
In this example, the Local Server is first in the search list. If a license cannot be found, the SideFX server will be used.
