Uninstall

Uninstall a J system by deleting the install folder, user folder(s), launch commands, icons, and shortcuts.

If you aren't sure where the J folders are, run J to get the information:
   jpath'~install'
...
   jpath'~user'
...
Don't delete the user folder if you want to keep those files for a new J install.

A multi-user install will have user folders in each users home folder.

Windows

Delete the J program group by clicking Start|All Programs then right clicking the J program group and selecting delete.

If you registered J as a COM server you can unregister it by running
....> [path to J install folder]\j.exe /unregserver
