[Bf-committers] bpy.dll

[Daniel Tavares]

Which of the Python runtimes were you running when you got the ImportError?
It seems to me that you're trying to import bpy from Python 2.6. That will
not work.

Make sure to import bpy from your Python 3.2 runtime. As Campbell said:

Execute...
C:\Python32\python.exe

>>> import bpy
>>> print(bpy.data)


Cheers,

Daniel
