That's my understanding for what is happening as well. Two follow-up questions:
1. Who should I ask about what I can do to suppress the "app compat goo"? I realize this isn't directly a WiX--or perhaps even MSI--question, but I wanted to start here in case I'm going about it all wrong. 2. What are your thoughts about my VersionNT64 conditions? Is this a reasonable thing to do? Or am I committing some kind of newbie faux pas? --Quinton -----Original Message----- From: Rob Mensching [mailto:r...@wixtoolset.org] Sent: Thursday, June 25, 2009 9:08 AM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Enforcing x86-only and x64-only installs I think that is a Windows Installer message coming up first and then the app compat goo kicking in saying, "Ooo, ooo, your install failed would you like to try again with magic pixie dust and maybe it'll work this time?" even though it won't. <smile/> That's my best guess.
