21. Register for free account.

22. Click Create Networks

24. I use "Accept automatically" setting join requests, so i don't have to accept every user that joins to my network. If you want to be sure that only your friends can connect to your network, select "Must be approved".

Network password is that password that you give to your friends, so they can join to your network. Select free subscription and hit Continue.

27. Open Hamachi and click Join an existing network, fill your network id and pass to input fields and hit Join.

28. Green icon on the left side of your network name shows that it works.

29. Go to Network and Sharing Center and click Change advanced sharing settings.

30. Select Turn on file and printer sharing and Save settings.

31. Last thing what i do is that, i add Hamachi's two executable's to my internet security's trusted application list.

NAT-Routing and port-forwarding

If your internet connection is NAT-routed, it is possible that you have to add port-forwarding settings to your router. Here is the ports that Hamachi uses:
TCP 12975 (initiator port)
TCP 32976 (session port)
UDP 17771 (relay connection port)

I checked my network monitor:

Hamachi is currently using 12975, but its good to forward all of those 3 ports. So that's it! Me and my friends setup Hamachi like this, and we can ping each other and see created LAN games. We have played Torchlight 2, WarCraft 3, Supreme Commander 1, etc. You should be able to play all LAN games if you do all steps right!
