VSTO Deployment not working on Computer without Visual Studio

I have written a Outlook 2007 Add-In. I added a Setup Project to it, and it built the dependencies itself.

When installed on a computer without visual studio, I get the following error message in the "Trust Center COM Add-in Manager":

"Load Behavior: Not Loaded. The Managed Add-In Loader Failed to Initialize"

Detected Dependencies

VSTO Redistributable wasn't selected in the prerequisite.
