Norton Ghost stuck in un-inmstall

WinXP SP3

Ghost 15

 

I was uninstalling Ghost 15. I did remove the external USB drive it was backing up to ( swapping out PC). I keep getting a looping error 1720 (Screen shot is attachment). It says an uninstall script error. How can I clear this and complete the uninstall?

Maybe this will work...

I tried it but the un-install was too corrupted. I was able to do a  system restore far enough back to clear the error.
