FIXED:
This error is most likely caused by the Background Intelligent Transfer service being stopped (and or disabled).
The reason other users have reported that it works when logging in on a different user account (like local administrator) is just that the service probably was not disabled on that account.
Start services.msc and go to the properties of the BITS service, and re-enable or re-start it.
The installer will then be able to connect to the internet.
Cannon, you should really write installers that don`t depend on Operating System services/components. This is an entirely unecessary requirement that just makes your software unreliable.
