Which CS6 the subscription version 13.1.2 or the perpetual Mac version 13.0.6. On a PC what did you use. When I install CS6 perpetual on a PC Photoshop CS6 64bit and 32bit versions were install along with Bridge CS6 64bit and 32bit. The Creative Cloud desktop can install Photoshop CS6 buit only has a Bridge CC option and Bridge CC have been updated toe use Photoshop CC 2014 instead of Photoshop CC. So if you want Bridge CS6 you need to Install PC Perpetual CS6 188.8.131.52
Mac Photoshop CS6 has no 32bit option old Mac 32Bit plug-ins can not be used on a Mac. I have never install CS6 on a Mac.
