It is available in a downloadable version which can be purchased through Mansfield Software Group's web site, and on CD.
To install KEDIT for Windows, simply run the downloadable module that
you receive or insert the CD into your computer's CD drive, and then
follow the on-screen instructions.
One of the questions that the Setup program asks is what directory KEDIT for
Windows should be installed in. By default, KEDIT for Windows is installed in
the \Program
Files\KEDITW, and we recommend that you accept this
default. In particular, you should not install KEDIT for Windows into the
directory where KEDIT for DOS or KEDIT for OS/2 is already installed, since the
files from the text mode and Windows versions of KEDIT should not be intermixed.
