What VE version are you using, and which package did you download (exactly, if you can remember). Did you upgrade from an older version of anything?


Finally, if it's an option, I have recently installed using the Python 2.5/win32 instructions and verified that they work for me. That route might work better for you if you don't have too much software that couldn't stand a little upgrade...

Hope this helps.

    Hi Dave,

    This is hard to debug, but it looks like there's an incompatibility
    between some of the modules you've installed.  In an attempt to
    narrow
    it down, could you try putting print statements in your script to
    see at
    what command it crashes? Typically, I've seen these most often
    when the
    version of Numeric used is different than the version that
    PyOpenGL was
    compiled with.

    As far as py2exe -- I haven't used it in a long time, but it did
    work...
