@Skybird to install CIS version 4 a complete uninstallation of the previous version is required. Updating to version 4 from previous version is not possible at all.
There are 2 ways to download the new ver 4 CIS.
One through web installer that requires the user to be online throughout the download and installation process.
Second downloading the needed files for an offline installation. I prefer the second than the first option.
