Rendering Add-In for Revit 2012 installation problem

Hello all,
I wanted to download the Rendering Add-In for Revit 2012.
I downloaded and when I run the installer, a dialog box opens showing me the following message:

Autodesk Revit 2012 Cloud Rendering
Has anybody else experienced the same? If yes then kindly tell me what to do next after this dialog box appears?
Waiting for your reply.
Take care and have a good day.
