So I have a 64 bit Windows 2003 system, running python 2.5.1.1.
I can import a Windows .dll (msvcrt or whatever) using ctypes, but
when attempting to import another application-specific .dll (tibrv.dll
if anyone is familiar with it), I receive the error WindowsError:
[Error 193] %1 is not a valid Win32 application.
I know there's a Windows on Windows (wow) which allows 32 bit
processes to run on 64 bit windows - is there a way to work this in
somehow? Maybe I'm barking up the wrong tree?
Code is simple, and works on 32 bit systems no
from ctypes import *
#this doesn't work
tibrv = cdll.tibrv
#this does work
msvcrt = cdll.msvcrt 6 18448

And by "works on 32 bit systems no", I mean "works on 32 bit systems
no problem."

Crap, no way to make a 32 bit load, even using the wowexec?

With WoW64, you can run 32-bit processes on a 64-bit system
(as you do all the time). That's all it does.
You cannot load a 64-bit DLL into a 32-bit application, or
vice versa.
If you want to load a 32-bit DLL on Win64, use the 32-bit
Python.

Martin

No. In Win64, a process is either entirely 32-bit, or entirely 64-bit. To
do the kind of crossing you seek, you would need to create a separate
process for the 32-bit DLL and use interprocess communication.

Shoot. Alright, thanks for your help. I guess I'll have to roll out
a 64-bit version of the tibco software. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
