Downloaded the latest stable version 2.49b 64 bits and nothing In the command box appears as Python was not found.
With version 2.53 it gives that Python was loaded, but I cannot find and put to work any script to work.
I think that is enough, I quit and goodbye to Blender and Lux Render. The old rule in action:
"Why make it simple if you can complicate"
Stupidity also evolves!
