Norton 'stuff' can be a nightmare to remove,as it gets stuck in the registry,hidden files,and eventually causes a case of "boot through the monitor" syndrome in the worst case.
As suggested by ScottGem at an earlier forum responce,visit this site:

In the search box,type RNAV and click search.Have a good look around,it might help.
Dont know if your problem of install has anything to do with the fact that your using a back-up (burnt copy),but Norton is an odd beast to mess with.
Good look my friend,
