compile 32bit application in python for use on 64bit win machine

[miamia]

Hello,
I am using 32bit win xp pro and compiling my python scripts as exe
with py2exe. Everything works ok on 32bit windows platforms. But how
can I compile my program for use on 64bit Windows?

On 64bit windows this error occures in event log:
Activation context generation failed for "C:\Program Files\app
\app.exe". Dependent Assembly
Microsoft.VC90.CRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8"
could not be found. Please use sxstrace.exe for detailed diagnosis.

how can I run this program on 64 bit? thanks
