barfy,
I'm just about positive you will need to go online for a new activation code. I'd installed Hal on a computer and got the activation code on a different computer in the past. I just reinstalled windows, I have windows on the C drive and Hal on the D drive (Partitioned drive), the reinstall was because of a slowdown of Hal which so far seems to be fixed. I moved the old brain database into the new version of Hal and can see the old information coming through.
