[python-win32] py2exe com_server newbie problem

[Blair Hall]

Update
--------

I now have something working, but not everywhere :-(

I have two different machines, both Win7 64-bit (one professional the other
home), both with identical versions of Python 2.7.8 and py2exe 0.6.9.

I can create a COM server DLL on the machine running Win7-Home (machine A)
but when I try the same process on the one running Win7-professional
(machine B) it does not work in the same way.

After using py2exe on machine B I cannot get regsvr32 to register the
server on either machine. But when I use py2exe on machine A the server can
be registered (on both machines).

I have used Dependency Walker to look at what is happening and I see that
during registration an attempt to load zlib.pyd is made. This file is not
available, so I think that is causing an error message. However, zlib is
not actually needed, so the registration of the DLL then proceeds (after
clearing the error dialog) and is successful. The same thing happens when
de-registering the DLL.

I have no idea why zlib is required when building on one machine and not
the other. Can anyone suggest a reason?
