A few things I'd like to point out:
- Check the box saying "Disable vulnerable Windows services over Hamachi", this stops other members of your network from looking at your shared files.
- Use the Non-commercial (free for personal use) license unless you: a) Own hamachi. or b) Want to use the trial. It's alright if you use the trial, it just reverts to the free version after it runs out.
- Make sure everything installs properly (see last screen below).
