Yes, MSIs declare the architecture they support. X86 MSIs can't write to x64 locations. MSIs that target Alpha (now long deprecated) can't install on x86 or x64 or ia64 (also now deprecated?).
See the -arch cmd-line switch and Win64 attributes on various elements. _______________________________________________________________ FireGiant | Dedicated support for the WiX toolset | http://www.firegiant.com/ -----Original Message----- From: Walter Dexter [mailto:wfdex...@gmail.com] Sent: Monday, June 29, 2015 2:51 PM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] 32 vs 64 bit MSI? I know this isn't really specifically WiX related, but I also know you guys know lots of MSI and installer stuff. I'm seeing references to 32-bit MSIs vs. 64-bit MSIs. Is there actually something inherently architecture-related about an MSI, or is it just a matter of the 32/64 nature of the programs it installs? I could see it getting messy figuring out which part of the registry to put stuff in for 32 vs. 64 bit programs on a 64-bit platform, so I guess Windows Installer would need to know where to do registry entries. But how does it tell? Thanks! ------------------------------------------------------------------------------ Don't Limit Your Business. Reach for the Cloud.
