I recently updated to 10.4 and was hoping the 64 bit python install was automatic, but apparently it isn't. I can't remember what I did in 10.3.x to get the 64 bit python. Does anyone know how to install it so that C:\Python27\ArcGISx6410.4
is included? Is it a separate download and install? All I have been able to find is this link for 10.2.
In this link for 10.4, it says:
Background Geoprocessing (64-bit) is available as a separate installation on top of ArcGIS for Desktop
But I can't find anywhere on that page that says how to go about the "separate installation"...
