SCALE is licensed through a software mechanism. You will receive at the time of purchase a special file via email. This file is generated and sent automatically and based on records in the customer's computer and therefore can not be sent separately.

Here is how you become a licenced SCALES user:
1.) Download the software whenever you like, before or after you buy your licence, it will not influence your licence status, in fact, you may run several versions on the same licence and computer.
2.) Purchase one or more licences. The only identification needed is a valid email address. When your credit card has passed verification, you get personal codes, one for each licence, sent to your email address.
3.) Within a year from the date of your purchase, open an Internet connection from your target machine (or machines) and launch SCALES.
4.) Your licence is valid for one year. You will be offered a prolonging of one year for a cost of slightly less than 10 percent of the initial licence price .
5.) Enter your code, press "SEND" (see the picture below) and within a few minutes you receive a small key text file (SCA32.TXT) in your email letter box. If you have bought several licences be sure to fetch your key files from every different target computer.
6.) Now, copy this key file to any one of three places on the hard disc where you run SCALES:

and your SCALES dictionary is completely open!

Errors, except those depending on the users own computer system, is very unlikely to happen. Please check your Windows system, your sound card, your I/O status, your email address and other matters that may affect running new software on your computer. In fact, not one single problem has so far occured, that was not due to the user's own computer system.

Please also note that SCALES is not a textbook in musical theori except for music scales. The help texts (fully available in the demo) do merely treat program management and theory of the most important standard scales in western music.
