Best way to install NIS Netbook Edition on a PC running NIS 2009

Hello -

 

Normally i would auto update via my norton account but the purchase price for the Netbook edition was really low so i decided to go that direction.  My quandry is: What is the best way to install it - should i just try to install it and have the software detect and uninstall the other version or manually uninstall the other version and install the new software starting from scratch.  This is installing on a desktop PC - not a laptop (the offer said you could install it on PC's too).

 

Any help is greatly appreciated.
