that Bridge and ACR are totally independent of each other. The installation of ACR has absolutely NOTHING to do with Bridge. Nothing.
That is a bit strong to state
While I agree the installation of the correct ACR plugin according to the screenshot in your earlier post should solve Jan's problem Bridge needs the correct ACR plug in installed to view the thumbs correctly and you can use the ACR plug in via both PS and Bridge (even at the same time with one working in the background…). So you know I hate to disagree with you but Bridge and ACR are very much depending on each other
