It's an installation problem, or maybe you tried to "fix" the installation
yourself.  I will wager real money that it works if you say this:
   python vhd2h.py vhd.vhd vhd.h -o   

When you omit the "python" name, the operating system has to figure out how
to run the command.  It does that by looking the extension up in the
registry, finding the command to run.

In a CMD shell, do this:

  c:\tmp> assoc .py
  .py=Python.File

  c:\tmp> ftype Python.File
I'm guessing yours will print something like this:
  Python.File=c:\Python24\python24.exe %1

The %1 is substituted with the name of the script being run.  In this
example, however, the parameters are all discarded.  If you set this
instead:

  c:\tmp> ftype Python.File=c:\python24\python23.exe "%1" "%*"

The "%*" says "put the rest of the parameters here."
