Downgrading+Virtual+Weather+Station

Problem
I want to downgrade to a previous version of Virtual Weather Station.

Solution
> \Program Files\Virtual Weather Station Installer and delete this directory.
 * 1) Locate the Program Files directory on your computer and the Virtual Weather Station Installer File:
 * 1) Download an archived version of Virtual Weather Station here: http://www.ambientweather.com/arve.html
 * 2) Install the archived version into the same directory as the previously installed version of Virtual Weather Station.
