I had this trouble when I went from CS3, to PSCC on my PC, Win 7, 64 bit. Seems like I had to go into the registry and replace the reference to CS3 with same for PSCC, even after uninstalling CS3. After installing 2014, when I double clicked a raw image in Bridge, it would only open in PSCC, not 2014. I uninstalled PSCC, but it still tries to default there. Of course, it can't, because that program no longer exists. I need to redirect to 2014.
Help? Thanks.

Got the answer: regedit>HKEY_CURRENT_USER\Software\Classes\Applications\Photoshop.exe\shell\open\command. In this case, the only thing I changed from Photoshop CC (64 bit) was to delete (64bit) and replace with 2014. Problem solved.
