It sounds like you are almost there, the trick is to use * as your component guids then wix will get it right for you (shared components will use the same guid as determined by the keypath).
http://wyrdfish.wordpress.com/2011/01/05/32-and-64-bit-msis-from-a-single-sou rce-file/ I also use a launch condition to stop the 32bit MSI being installed on a 64 bit OS then you don't have to worry about shortcuts. But if you do want to allow them to be installed side by side you would have to create a 32 and a 64 bit shortcut folder to stop them clashing. -----Original Message----- From: Dave Mateer [mailto:dave_mat...@ntm.org] Sent: 12 March 2012 18:36 To: wix-users@lists.sourceforge.net Subject: [WiX-users] 32- and 64-bit installers: which GUIDs should be unique? I have a working installer and have been using this installer for both 32-bit and 64-bit, simply switching the "Program files" location, i.e.: <?if $(var.Platform) = x64 ?> <?define Win64 = "yes" ?> <?define PlatformProgramFilesFolder = "ProgramFiles64Folder" ?> <?else ?> <?define Win64 = "no" ?> <?define PlatformProgramFilesFolder = "ProgramFilesFolder" ?> <?endif ?> We just discovered that Weird Things Happen when both the 32-bit and 64-bit are installed, then uninstalled in various orders, etc. The files in "Program files" are obviously installed in separate locations, but some of the content is installed in the same location, i.e. "CommonAppDataFolder". My question is, to save myself the most amount of pain in the future, which Guids should be the same between the 32-bit and 64-bit versions, and which should be different? For those that are different, how can you code this in WiX without maintaining two completely separate installers? We would like to support both major and minor upgrades, and although we don't want people to install both the 32-bit version and 64-bit version and run them side-by-side, it is really outside of our control and ideally that shouldn't break anything, nor should uninstalling one version break the other. Here are my guesses so far, but I really don't have much confidence in my understanding: +---------------------------------+---------------+-------------------------- ---------------------------+ | Value | x86/x64 same? | How | +---------------------------------+---------------+-------------------------- ---------------------------+ | ProductCode No Use * as ProductCode | | UpgradeCode No Define different static Guids in config file | | Files in "Program files" No ??? Would I have to define every single file twice? | | Files in " CommonAppDataFolder" Yes Hard-coded Guid | | Shortcuts (shared) Yes Hard-coded Guid | +---------------------------------------------------------------------------- ---------------------------+ Please enlighten me!
