It demands a reinstall? Are you trying to go from Vista 32bit to Windows 7 64bit? Because that'll definitely ask for a reinstall. Going 32bit to 32bit though should work though.
Also just getting back to my superhub - I haven't had a chance to look at it properly yet, but this is what it currently looks like (Apologies for the poor quality):
