I wish to reinstall NIS on the Windows XP computer I just removed it from

I am suffering through the latest conflict with NIS and an older windows XP machine . I removed NIS then ran the norton removal tool. I went to account management to try to reinstall it but it says "You do not have any installs remaining." You can protect more devices by purchasing more installs." It also still lists my XP machine as one of those installs. All I want to do is reinstall it annd do manual updates to avoid the latest patch untill a fix comes out. Any Ideas?
