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. Press the "Local Server" button.
