DFF is an executable program running on Windows or Linux platforms. You must register an account on the DFF website to access the software and obtain a license.

Once signed up, you can download DFF installation packages. Select your desired platform to download the installer.

Run the installer to set up DFF on your computer.

When you run DFF for the first time, a dialog will appear to generate a license request. Follow the instructions to fill out the request form and save it as a text file, then upload the license request file to the DFF website to obtain a license.

A one-month free trial license is automatically generated. After the trial period, a perpetual license can be purchased by contacting distributors in your territory (China, Japan, or the US for all others) for pricing and available editions.

Any license includes one year of free updates. A notice will be sent to you when a new version is available for download. After one year, an additional update fee is required.
