I have Adobe Bridge CS6 32-bit and 64-bit installed. I prefer to use the 64-bit version, but whenever I right-click a folder in Windows Explorer and choose 'Browse in Adobe Bridge CS6', the 32-bit version always opens. How can I make this default to the 64-bit version? There doesn't seem to be a way to uninstall the 32-bit version.
Edit your System Registry on:
Change the path that is pointing at 32bit version and set it to point at the location of 64bit version:
C:\Program Files\Adobe\Adobe Bridge CS6 (64 Bit)\Bridge.exe "%L"
If you open Bridge and double click on an image will it open in PS6 64 bit? If not you should be able to change your preferences in Bridge. Click edit/preferences/file type associations. Click the radio button at the bottom first and see if that works. For most users CS6 64 bit is the default setting.
If it opens find from there then you will have to change the file association in the OS. Click on the OS help to see how to do that.
