1. Enter the download site, and start the download.
2. When it asks you to Save or Run, we recommend that you Save it. [You can click Run if you want, but if you have problems installing you will end up downloading it again.]
3. Once your download is finished, run the installer. Depending on your computer, it may take a few minutes for the program to load. This is normal.
4. Once it is installed, go to the directory where you installed the game.
5. Run Flyff.exe, and welcome to Fly For Sky! [You can make a shortcut of Flyff.exe, and rename it.]
