Move the files InstallScript and AWUPD.lha to the directory
containing AWMWB2.lha!  You can do this by dragging and dropping.

You will need 300 to 400k of disk space to update the archive.

You may delete any *extracted* archive of AWMWB2.lha.

The script will create the AWMWB2_1.lha archive, and an extracted
directory containing AWMWB2_1.

Double click on the InstallScript icon to begin the installation.
Make sure lha and iconx are in your c: directory or in the commmand
path (they should).
