After downloading, double-click on the downloaded
file to install Ultra Fractal. Follow the instructions
in the setup program.
If you are installing Ultra Fractal 2 or 3 on Windows Vista or later Windows versions, you will need to run the installer as an administrator. Starting with Ultra Fractal 4, this happens automatically.
If you want to install multiple versions of Ultra
Fractal on the same computer, it's best to start
with the earliest version and then install later
versions. For example, first install Ultra Fractal
4, and then Ultra Fractal 5.
