Version of Application Verifier to use

[jcec]

Greetings,

If this is not the right Group for the question, please tell which one
should I post to.

I am developing a:
- mixed-mode application (C#, C++/CLI, native C++)
- compiled to 32-bit
- deployed to a X64 PC platform
- running Windows Vista 64-bit OS

I intend to run Microsoft Application Verifier in that platform to pinpoint
memory errors and leaks in the native-part of my application.
Which version of Application Verifier should I use, X86 or AMD64 ?

Thanks for your attention
