Windows 7, run the MSI as administrator. Older Window versions, log on with administrator rights.

The MSI file is much like the ISO image with two main exceptions:

1. You do not 'mount' the MSI image, just double click it
2. It does NOT include the prerequisites that the ISO image installs, therefore you must have the following already installed:
• .NET 2.0 Framework
• Microsoft Windows Installer 3.0
• Microsoft Security Update MS04-011

Once you have downloaded the MSI image, double click it and you will see the following screen:

(NOTE: If you have a previous version of this interface already installed, you will be prompted to remove the previous version.  Please follow the steps to remove the previous version)

Now you can continue installation with the next screen being the EULA.
