The usual approach is to create 2 versions of your installer and sequence that with some kind of bootstraper that detects the machine bitness and launches the appropriate package.
You could use the new Installshield Suite project type to do this. I am currently using one to sequence a handful of 32-bit installers.
I also read somewhere that WIX has a new tool called Burn. (http://wixtoolset.or...nual/v3/bundle/)
I haven't used it but it is a free toolchain. I assume that the Suite Project provides functionality similar to Burn.Go to the full post
