The layout of the data that bdist_wininst collects has changed.
Unfortunately, the magic number '0x1234567A' hasn't changed, although it
should have been.  If it were changed, you would have seen a MessageBox
'setup program invalid or damaged'.  See the create_exe() method in

I will repair this in CVS.

The problem is that you subclass bdist_wininst in the PyOpenGL setup
script, and have to make these changes yourself, for Python 2.4.
If it helps you, I can factor out a get_installer_filename() method in
the 2.4 version.
