Save settings-upgrading from prev.version

Is there a way - aside from exporting from registry (HKEY_LOCAL_MACHINE\SOFTWARE\Eset) to save personal settings (slightly modified Blackspears when upgrading for. e.g- from 2.70.16 to 2.70.23?
When I tried to install 2.70.23 upon 2.70.16 (hoping that this way I can preserve my settings, just like in case of Outpost install) I got an error message and only uninstall and fresh install worked...
Is there a more simple - cute - workaround 4 this?
Thanx in advance!

 

I alway use the exporting way of preserving the settings, but when upgrading, it won't work anymore as you should always export the registry settings again for the new version, otherwise it will still show the old version.
