# Activate the STPI Secure License

### Purchasing a License 

Before a license can be activated, it needs to be purchased and created for you. Please contact the PayFacto Boarding team or your local Sales Representative to purchase a STPISecure license.

***

### STPISecure License File 

After you have purchased a STPISecure license, the license file will be sent to you as a text file attachment via e-mail. The e-mail will come from the PayFacto Boarding Team or your local Sales Representative.

1. Save the file from the e-mail to your Windows Desktop. Typically, the file is named something like "Licdefault\_12345.txt".&#x20;
2. Rename the file to "Lic.txt". To achieve this, you can right-click the file and select the Rename option, or select the file and press the F2 key on your keyboard.
