Transferring Hamachi2 settings between two computers.

To transfer the Hamachi2 settings from an old install to a new, first Install Hamachi2 on the new machine.  Recommend that you use the included hamachi.msi installer for this, so we're definitely using the same version: Hamachi 2.0.2.85.

Then, close the Hamachi UI.  Go into services and stop the LogMeIn Hamachi 2.0 Tunnelling Engine for now.  Now, copy/overwrite from the old machine to the new machine the following directories:

On Windows XP:
C:\Program Files\LogMeIn Hamachi
C:\Documents and Settings\{yourUsername}\Local Settings\Application Data\LogMeIn Hamachi
C:\Documents and Settings\LocalService\Local Settings\Application Data\LogMeIn Hamachi

(to do: Windows 7)

With this done, start the tunnelling engine service again and fire up the Hamachi2 GUI.  It should now connect as the same IP as it did on the old installation.
