I need to use a toolbox that has not yet been upgraded to be 64 bit background processing compatible. Is there any way to downgrade to python 32bit 2.7? I would be willing to even install another version of ArcMap to get this toolbox. The toolbox is essential for my research. They are working on a 64bit, but I do not know when they will be finished.

Hi Anthony, it sounds like you have both ArcMap and the 64-bit background Geoprocessing patch installed. If my assumption is correct you have both 32-bit and 64-bit Python already installed. It may just take some coding updates to call the 32-bit libraries. 

Here is a very good source of information about identifying and calling the right Python bit level:

The article below explains how you can call 32-bit directly:

Note: it says Server and Desktop but the same rationale should apply here
