Updates to clonecd

I have purchased and registered a copy of clonecd. Very happy with it so far. My question is about updates. If a new version is released will it install over the old version or do you need to un-install the old and do a clean install of new? My system is Windows XP home. Any hints tips such as reboots and other info would be appreciated. Of particular concern is the saving of existing profiles when upgrading. Do you have to save them and move back to the clonecd directory or are they not disturbed during updates.

Thanks in advance for your help.

just install over it, and it wil keep the settings (and images)
