How to download SimCCDWarning: SimCCD is supplied as a zip archive. The files in this archive MUST be unpacked into a regular Windows folder. If you do not do this, Windows will present the files as if they were in a regular folder, but when you try to start SimCCD by double clicking on Run SimCCD.vbs, it will complain that Java may be missing, even if you have installed it.
To have Windows unpack the zip archive, right click on it, select Extract Files, and follow the instructions. MacOS users will have to extract the files too, for example by using StuffIt Expander; and Linux users will have to extract the files using the unzip command.
