[mod_python] Trouble with Apache 2.0.54 and Python 2.5.1

What was the name of the mod_python installer  you used? Did you
definitely use the version for Apache 2.0/Python 2.5?

Is there any other python25.dll files on your system anywhere? Some
third party Windows applications use Python internally and provide
their own python25.dll. If that is in a directory on PATH found before
the system directory version, it can cause a failure.

Other than that, only other suggestion is that if running Apache as
service, that the user it runs as has adequate permissions to read
mod_python and Python installed files.
