How to play Heroes of Might and Magic III online via Hamachi?

guys, please help! I don't have Hamachi, but my friend does!

Here's the problem: when connecting in Hamachi, it shows an error:
Hamachi network adapter is manually configured with an IP address that is different from what Hamachi needs to use. Please switch the adapter to DHCP mode or configure it to use the correct IP address.

How can I fix this?
