As far as I am aware, it is not possible/supported to install 32 bit components in a 64 bit MSI. There are unsupported hacks out there, but they would fail ICE validation and wouldn't be Logo certified.
If you already have a 64 bit and 32bit MSI, and the 64 bit MSI installs only 64bit components, then it would be near trivial to setup a Bundle to do the registry searches you previously wanted to do in a MSI and conditionally install either the 32 bit or 64 bit MSI on a 64 bit machine. In addition, this same bundle can be deployed to a 32 bit machine. -----Original Message----- From: Tim Hawes [mailto:haw...@anx.com] Sent: Tuesday, June 18, 2013 9:58 AM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Java Program Installer My understanding is that a 64bit installer can install 32bit binaries? I am using this just for 64bit systems. I am already building a separate 32bit installer for 32bit systems (which only needs to test for JRE version). The problem I describe below is a 64bit installer which must determine which JRE is installed on the system, since it is possible to install both a 32bit JRE and a 64bit JRE. If I need separate installer for this, then forget it. It will just have to fail if it doesn't find the 64bit JRE.
