I just discovered something trying to do a clean uninstall and reinstall of SW due to some toolbar corruption. If you dont transfer your license to SW before the uninstall, you will not be able to delete SW from the registry under HKEY_LOCAL_MACHINE. RegEdit told me it couldnt delete the key. It was not a permission idssue either as I tried under Admin, and tried changing permissions. SW says you only need to transfer licenses when upgrading hardware or installing on a new computer. I think they need to change that warning to include doing a clean uninstall. Or they could just delte the key, I mean after all, I did chose to uninstall.
