What version of SAV are you trying to install and on to which operating system are you trying to install it?
Nonav was a removal utility that is no longer used and it is not recommended to be used anymore. Cleanwipe is the current removal utility used to assist in removal of SAV and SEP. SymNRT, designed to remove Norton products, is also available through Support.
If you don't want to call in, you can open a case via MySupport.
