Upgrading computer from XP to Windows 7

[MungoP]

My XP machine has been giving me boot problems
so I bought a new machine with Windows 7.

Question How do I go about getting my Map Source,
City Navigator and OZ Topo 3.0 across to the new box.

It would be lovely just to re-install from the original disks
with all the magic numbers but life wasn't meant to be easy.

Maybe I need to uninstall with the internet connected
so my installation usage count can get reduced by one
at Head Office (that is apparently the case with Nuance
Dragon Naturally speaking). Hopefully I can reboot the XP
and do that.
