Dell System Detect: Application cannot be started. Contact the application vendor, using Windows 7 Home Premium.

I cannot run DSD, i cannot uninstall DSD therefore I cannot update drivers or use anY Dell updates or downloads.

I cannot contact application vendor unless i pay for a diagnosis yet it is Dell's software that is causing my issue.  Error Summary indicates - The deployment identity does not match the subscription  not sure what that means?

Details from the message box is as follows -
