How To Install NIS on WinXP Home?

[weeGeordie]

I've installed Norton Personal Firewall using one of three id's on a WinXP Home SP1 system. When I switch to one of the other id's it tells me the O/S has been upgraded since Internet Security was installed and I have to uninstall/reinstall.

Is there a process to installing software on a multi-use WinXP system that I have missed?

THanks ...

Did you install it while logged in as administrator ?

The account I used had administrator privileges
