Thanks, Phil. Because I do not have a Bundle, which serves as the arbiter for choosing which bitness to install, a user can download each version: 32b and 64b. I think you are able to give them the same UpgradeCode because they will never be able to be installed at the same time due to the Bundle's conditional logic.
If I give each version the same UpgradeCode, there is not change in behavior. Both versions can be installed at the same time. If I put the 32bit UC in an Upgrade element in the 64bit, there is no effect. If I put the 64bit UC in an Upgrade element in the 32bit, there is not effect. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/How-to-Prevent-32bit-and-64bit-MSIs-with-Different-UpgradeCodes-and-Dynamic-ProductCodes-from-Both-Bd-tp7596280p7596285.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
