I ran the Vista Upgrade advisor a few weeks ago and it says that Norton is
not compatible with it, below is what it advised me to do

This program must be uninstalled before upgrading to Windows Vista. After
upgrading, you will not be able to reinstall the program due to
compatibility issues. For more information, go to the vendor's website.

If you go to the vendor's website, in this case Symantec it takes you to a
page that scans your PC to see what Norton Products are installed, so to see
what upgrades it needs to do.

My question is, if I have just installed vista and I can't reinstall Norton,
it wont know what updates to perform as it wont see any Norton Products.

So how do I get round this, thanks in advance
