Hello,
I have a 64 bit windows but run python 32. What installer do I use?
Panda3D ships with its own copy of Python 2.7. 64-bit Panda will ship with a 64-bit copy of Python, so you can use that just fine.
If you insist on using your existing 32-bit Python 2.7 installation instead of Panda’s, then you would have to install 32-bit Panda.
This is awesome! 
Just tried the dev branch… and as a game engine hobbyist and dev I did notice that Panda3d and Ogre3d now has the same stable release with 1.9 
Excellent work! Keep it up.
