Error Code 2753

I can't install Internet security 2008. I had it installed but I started getting the 404 error on updates. I thought maybe something got corrupted so I tried to do an uninstall which I guess crashed at some point. Now when ever I try to re-install the installer thinks it is already installed and only gives me the option to "repair" or "remove". I tried both but after each reboot I get the same thing. I downloaded the uninstall tool and it says it uninstalls but after the reboot I still can't install.

I downloaded Total Security 2008 and that will install but at some point I get error code 2753.

Can anybody help with getting Internet Security 2008 installed again. I own that so that is the one that I have to use

THanks
