In versions prior to Houdini 19.0:

The Houdini License Administrator can be told to use an HTTP proxy to access the internet if your site is configured this way.

1. Find out your HTTP proxy host name and port by looking at your web browser's settings
2. Select File -> Preferences... in the License Administrator
3. Turn on the toggle to use an HTTP proxy, and enter the proxy host name and port

These settings will be saved for the next time you use the License Administrator.

If you require a login to use Proxy at your site, the HTTP Proxy in the License Administrator will not work. You will need to follow the section How do I install licenses without Internet Access.
