1. Install
2. Start the provided RLM server (or set it up as a service) to serve the sfx_server.lic
3. In the Silhouette Activation screen choose "Advanced options" and in the next step point 
   it to your license server with "5053@localhost" (or whatever port and server you're using)

When in doubt check the inlcuded manual.

NOTE: Silhouette uses RLM v12. If you have a running RLM setup with an older version of RLM
you can replace that rlm binary with this newer v12 to serve your other RLM licenses.

NJoy!!
