The qualifying product is Photoshop CS6. Nothing else will solve the problem you have. It is not caused by having previous versions of the Adobe products installed.
It is also likely that even then, it may not solve your problem. Bridge (and Camera Raw) are installed by a variety of Adobe products, but to use Camera Raw via Bridge at a minimum you will have to start Photoshop CS6 at least once.
If you want Camera Raw to open Tif files you have to set the Camera Raw preferences to so rather than Photoshop.
