# Create a directory '''outside''' of the application's installation directory to be updated (e.g. <code>C:\app-update\</code>). This directory will be referred to as the '''outside''' directory throughout the instructions below so please make a note of its location. Grant the user account you are using Full Control permissions on this directory if it doesn't have these permission already.

# Copy <code>updater.exe</code> from the application's installation directory that is to be upgraded into the '''outside''' directory. If you would like to display the updater user interface while it is applying the update also copy the <code>updater.ini</code> into the '''outside''' directory.

# Rename the mar file you downloaded to update.mar.

# Open a command prompt by running cmd.exe. On Windows Vista or greater you may need to launch cmd.exe with "Run as administrator" (available in the context menu when right clicking cmd.exe).
