Correct me (someone) if I'm wrong here but, are'nt these type of files self installing normally? Just go to Nova, or a resource site (like errrrrm, this one) download the update file, unzip it to where it tells you and then after it's downloaded, run the setup or .exe file. (I usually unzip files to a folder I created within "my documents" which I then empty afterwards so I know which files have been unzipped next time) Does any of this make sense? I hope it helps
