So… I figured I’d post an update (even if it is a few months old) regarding Hamachi and running it as a service under Windows. LogMeIn updated their licencing to a commercial/non-commercial system as opposed to the basic/premium setup. There’s no difference in functionality now, but it’s assumed that if you use Hamachi in a commercial environment, you’ll pay for it.
That being said, it’s quite easy to run Hamachi as a service now. Click on the gear in the main Hamachi window and select “Preferences” to bring up the configuration options. Under “System”, click on the button that says “Run Hamachi as a Windows Service”. It will restart Hamachi, and voila!
