Pharaoh - Build a Kingdom. Rule the Nile. When downloaded, it checks Windows registry for the location of the Pharaoh demo and installs its files there. Note that the pharaohdemo2.exe file must be downloaded and installed before either of the add-on downloads are installed. The addons can be installed in any order providing that pharaohdemo2.exe has already been installed.
Players can uninstall the new demo via the start menu.
The uninstall will also remove all of the files from either of the add-ons.
