I did everything you suggested and I am certain we are close, however now I can open Photoshop CS6 32bit and then File/Automate/Daz Studio 3d bridge.

The menu opens in the upper left and immediately opens Daz Studio 4.21 64 bit but the bridge is not activated.

When I go as Photoshop instructs me to Daz3d, there is an error message:

"Could not open file: scripts//init 3dbridge.dse. File does not exist."

Sooooo close....
