Need help reloading Dell apps after downgrading from Win 8 64-bit to Win 7 64-bit

Can someone help with my software issue? I installed windows 7 ultimate on my Dell Inspiron 15r 5521 and reinstalled all drivers and chipsets. However, when i try to download the third-party applications that were preinstalled with Windows 8 I downloaded the SmartSource media manager (http://smartsource.dell.com/client/SmartSource.MediaManager.application?t=92cc1d56-9ce0-47b1-8889-858fe498b68a&m=1) but  I receive an error message "Cannot download the application. The application is missing required fields. Contact application vendor for assistance." The details are:
