Note   The trial version of CyberSky is guaranteed to be safe and clean, completely free of adware, malware, spyware, and viruses. The program does not make any unauthorized connections to the Internet.

Installing the trial version

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

During installation, the setup program copies CyberSky to a folder on your hard disk, adds CyberSky to the Start menu, and optionally puts a shortcut to CyberSky on the desktop.

After you install CyberSky, you don’t need the setup file to run the program, so you can go ahead and delete it.

Note for CyberSky 1, 2, or 3 users

The setup program installs the latest version of CyberSky in a different folder than previous versions of the program. You can have CyberSky 4 and CyberSky 1, 2, or 3 installed on the same computer, and can use both versions at the same time; the two programs won’t affect each other at all.

Uninstalling the trial version

CyberSky includes an uninstall program that allows you to remove the software from your computer if you don’t like it or it doesn’t meet your needs.

To uninstall CyberSky from your computer, on the Start menu, point to All Programs, then point to CyberSky 4, and then click Uninstall CyberSky 4.

The uninstall program removes only those files that were originally installed on your computer. If you’ve saved any maps as CyberSky Map files or as image files, you must remove these files yourself.
