The downloaded Castanet tuner is a compressed tar file that installs like most similary packaged applications.
Installation takes just a couple of minutes.
If you print this page, installation will take up less screen space, and you'll have a convenient place to check off each prerequisite and installation step as you complete it. If your computer is behind a firewall you'll need to provide the Tuner with proxy information. You can get this information from a network administrator, or from a Web browser that you know can reach the Internet. If No Proxies is selected, your site does not use an HTTP proxy. If Automatic Proxy Configuration is selected, open the URL listed next to it with your Browser and write down the HTTP proxy's host name and port number.
