Installing the update

To install the CyberSky update on your computer, download the patch file, double-click the file to start the patch program, and then follow the instructions that appear.

During installation, the patch program modifies or “patches” the CyberSky program and Help file installed on your computer so that both include all of the improvements introduced in newer releases.

After you install the CyberSky update, you don’t need the patch file to run the program, but you should save it in case you need to reinstall CyberSky.
