How to use photoshop 32bit instead of 64bit?

I’ve got the Adobe Master’s collection installed on 64bit Windows 7. Whenever I install photoshop it automatically installs the 64bit version and the the 32bit version. I’ve associated all of the image files in Adobe bridge with Photoshop 32x manually but I can’t find any way to set Windows associations through control panel. Whenever I decide to set associations with Photoshop 32x it doesn’t change, it just keeps it at 64. It’s as if there isn’t any Photoshop 32x icon in the “Open with” menu.
Is there any way to completely disable photoshop 64bit or set all the associations to 32bit? Half of my plug-ins don’t work with 64 and I haven’t had much luck getting it to work normally either.

Sounds stupid, but did you try uninstalling it, downloading just the 32bit and installing that?
