If you follow the component rules then yes: this should work. The contents of MAINFEATURE should be identical between INSTALLERA and INSTALLERB, including the directories used and the GUIDS of the included components, as well as the associated keypaths which must also be identical.

Subject: [WiX-users] Quick Question: common features in multiple installers Hi Wix users, before I sink time into authoring installers and testing, I am seeking your comments wether the following concept could work, or wether I have missed something. Assuming I have an INSTALLERA.msi, which consists of the features MAINFEATURE and DATA1 and DATA2, and another INSTALLERB, which consists of the features MAINFEATURE, DATA3 and DATA4, Mainfeature is identical in both installers, and has the same GUID. I do use the FeatureTree UI, and author a conditional install for MAINFEATURE in both installers, so it will be installed only once, and since the feature is identical in both installers it does not matter which installer is executed first. The objective is: INSTALLERA and INSTALLERB may be executed by the user in any order, and there is no need to install both. A typical situation where a sofrtware product is sold in modules. MAINFEATURE is mandatory, and must only be installed once. If the user leaves all settings on the defaults, MAINFEATURE will be installed long with the first of INSTALLERA and INSTALLERB, whichever is installed first. If a user installs either INSTALLERA or INSTALLERB, but not both, everything is easy, he geths the MAINFEATURE and the DATAx according to the installer he has executed. I am concerned if he installs both, in either order, whether, if, during uninstalls, the Installer is smart enough to uninstall MAINFEATURE along with the latter of both Installers, even if this is not the installer which has originally installed the component. I am not quite sure weither I expressed myself clear enough (sorry - natively I am German ....), so the following table should make things clear: user installs INSTALLERA with all features enabled, on his computer, and he gehts MAINFEATURE DATA1 DATA2 then he installs INSTALLERB, and has MAINFEATURE DATA1 DATA2 DATA3 DATA4 Now he uninstalls INSTALLERA to get rid of DATA1 and DATA2, and - hopefully - ends up with MAINFEATURE DATA3 DATA4 and only if he then uninstalls INSTALLERB too, MAINFEATURE gets finally uninstalled along with DATA3 and DATA4. Any chance this is going to work?
