We use offline authorization method to license our customers. An authorization file is a file containing the information help to complete the authorization process in your computer. It is generated with the machine code of your computer by some special encryption algorithms.

After you obtain the authorization file, put it into the folder [MT4 Data Folder]\MQL4\Files. The program will read authorizing information from the file and finish the authorization process.
