No module named direct.directbase.DirectStart

Hi,
just installed Python23 and “panda3d-2004-07-16A.exe” from the Download Section of the site “SDK Downloads | Panda3D”.

Then I switched to path “C:\Panda\samples\BVWTutorial” and tried to start the “PandaDemo.py”. My IDLE goes up telling me this:

Traceback (most recent call last):
File “C:\Panda\samples\BVWTutorial\PandaDemo.py”, line 1, in ?
import direct.directbase.DirectStart
ImportError: No module named direct.directbase.DirectStart

If I look into the Panda paths, I cant find any “direct.directbase.DirectStart” anywhere. I only get the src paths. Since I downloaded the binary version, I assumed there is the running version installed.

What am I doing wrong ?
