Most licensing issues can be resolved by referring to the Common Licensing Problems page.

If you cannot resolve your licensing issues, please email support@sidefx.com with the license diagnostic from the machine you are trying to license. Please also include your Account number and or/email used for licensing so the support team can easily locate your account information.

To generate the license diagnostic:

1. Start the Houdini License Administrator (hkey)
2. Under the View menu, select "Diagnostic Information"
3. Save the file and attach it in an email addressed to support@sidefx.com

If you don't have a graphical display, you can type "sesictrl diagnostic > diagnostic.txt". Attach the diagnostic.txt in an email to support.
