Nero 8 not installing

Hai,
I installed nero 8 in my winxp sp2. Then i uninstalled for some purpose.
if i try to install again, it says nero setup was interrupted, run the setup again. i tried lot of times, but i am unable to install. i consulted with my friend, he told me to delete previous nero entries in registry. i cleaned with registry cleaner. but still i cant. any body help me.

thanks in advance.
