Selector is not provided to individuals, only to qualified broadcast entities or consultants.
Free trial copies of Selector (a complete, working program) are available as well. To learn if you qualify, just contact us
http://www.rcsworks.com/en/company/contact.aspx and an RCS Sales rep from your region will contact you directly and quickly.
However, many stations authorize their programmers for additional copies of Selector for use from home, laptops or elsewhere, so you could certainly learn on your own in that manner.
