Do I need to uninstall a previous version of CyberSky before I install CyberSky 4?
No. There is no need to uninstall CyberSky 1, 2, or 3 before installing the latest version of the program. CyberSky 4 will be installed in a different folder than a previous version of the program, and won’t affect the older version at all. You can choose to keep the previous version of CyberSky on your computer or remove it.
