There are three ways to uninstall jEdit and jEditLauncher.
First, you can run unlaunch.exe in the jEdit installation directory.
Second, you can choose Uninstall jEdit from the jEdit section of the Programs menu.
Third, you can choose the uninstall option for jEdit in the Control Panel's Add/Remove Programs applet.
Each of these options will deactivate jEditLauncher and delete all files in jEdit's installation directory. As a safeguard, jEditLauncher displays a warning window and requires the user to confirm an uninstall operation. Because the user's settings directory can be set and changed from one jEdit session to another, user settings files must be deleted manually.
To deactivate jEditLauncher without deleting any files, run jedit /u from any command prompt where the jEdit installation directory is in the search path. This will remove the entries for jEditLauncher from the Windows registry. It will also disable the context menu handler and the automatic launching and scripting capabilities. The package can reactivated by executing jedit.exe again, and jEdit can be started in the same manner as any other Java application on your system.
