Is there a way I can edit the registry so that in Adobe Bridge, under edit, preferences, file type associations, the jpg extension is forced to use the 32-bit version of Photoshop? I can do it manually, but is there a registry key i can export to apply it to multiple computers?
The File Type Associations of Bridge are not writen into the registry. They are written into the Bridge Preference files.
As in that is a file located somewhere that I could get setup correctly on one machine, then copy to all the others to transfer those preferences? If so, where would I find that file?
Yes, in theory, but it is generally not recommended. But that location would depend on what OS you are on. This video give the locations for the Photoshop files, Bridge would just be in a neighboring folder: http://tv.adobe.com/watch/the-complete-picture-with-julieanne-kost/how-to-reset-photoshop- cs6s-preferences-file/
