Revit Architectural Suite 2011 Error on Installation...

Hello everybody, even dough this blog is not an Architectural Blog, this is a problem that I came a cross with one of our customers...
The problem was that every time that they were trying to launch the installation for Revit Architectural Suite 2011, the initialization was producing the following error:

There were no install logs, no events logged in the Event Viewer or any other helpful information. When checking the version of Windows Installer on the machine (XP), it was 3.01. The user upgraded to Windows Installer 4.5 and the error was resolved. Here is the link to download the installer base on your respective OS just in case...
Windows Installer 4.5 Redistributable
Hope this will help you regardless of the Application that you are using in case that you experience the same problem...
