MSI Installer for 64bit Windows Platform(Visual Studio)

I have a COM component which I wish to deploy in a 64bit environment. There are multiple applications using this COM component. Some of these applications are 32-bit and others are 64-bit. So while creating an installer, I which to bundle both the 32-bit and 64-bit versions of my COM dll. In my first attempt, while building the installer project, I get a lot of warnings:

Ex. WARNING: Two or more objects have the same target location ('[payload_ul]\msvcp90.dll')

The warnings above are to do with merge modules. I have checked, but no multiple merge modules are present.

Also while the projects compiles successfully though with the warnings, while testing I found that the 64 bit module had failed to register.

The MSI was marked for x64 platform.

Can anyone provide pointers for the correct way to do this?

MSI doesn't support mixed x86 and x64 installers (check out this blog: http://blogs.msdn.com/b/heaths/archive/2008/01/15/different-packages-are-required-for-different-processor-architectures.aspx ). There are ways to "workaround" it, but eventually you will be bitten one way or another.
