I just recently upgraded my KIS2012 to 2013. What I did was download, from the Kaspersky site the KIS2013. Then uninstalled 2012 with the option to keep/save the Activation codes. I think I rebooted, then installed the 2013, and was all set after it updated the database. Prior to that, I was paranoid that I lose everything, not have the activation code, and in general have one of my worst nightmares. -- Went through without a hitch. Hope this helps.
