Camera raw editing

Hi,

I'm using Bridge in CS6 in a 2011 iMac and have been getting the following message when trying to open an image in camera raw in Bridge:

Camera raw editing is not enabled camera raw editing requires that a qualifying product has been launched once to enable this feature.

Does anyone know of a fix or how to deal with this? I
'm trying to open jpegs and tiffs.

Thanks,
Michael
