You can access this dialog by selecting "Install/Uninstall" command under Tools Menu or clicking button on toolbar.

If you are running CooJah the first time, this dialog will pop up when start up. The purpose of doing this is to tell you that it may affect your system if it is used incorrectly. The first time when you run CooJah you have to click the Install button. Then you needn't click Install button anymore unless you click the UnInstall button mannually. There is an option named Uninstall on Exit. Click here for its meaning.

Either you get CooJah by installation wizard or copying from somewhere, do remember that you mustn't move it anywhere. If you must move it, do remember uninstall the sniffer first here. If you get CooJah without installation, you must also uninstall sniffer first before you can remove it. Otherwise, you may meet the network problem. The sniffer will be uninstalled automatically when you unstall CooJah with a uninstall wizard.

Urgent Uninstall is used only when normal Unintall fails.

All these operations need administration privilege.
