That's extremely enlightening. I thought having two components in different products with the same GUID but different installation directories would be a blatant break of component rules and would just not work. "Allowing uninstallation of shared component. Other clients exist, but installed to a different location." was totally unexpected to me :)
Is this documented anywhere other than blogs? I think I read *all* of Rob's blog. It looks like Heath Stewart's blog will be my next time sink. -- Nicolás 2013/10/2 Blair Murri <os...@live.com>: > See > http://blogs.msdn.com/b/heaths/archive/2009/12/21/about-shared-components.aspx > >> From: nicolas.alva...@gmail.com >> Date: Tue, 1 Oct 2013 00:51:36 -0300 >> To: wix-users@lists.sourceforge.net >> Subject: [WiX-users] Practical use of wixlibs >> >> I can't find any documentation on best-practices when creating either >> merge modules or wixlibs, only procedure documentation on how to >> create them. >> >> Let's say I create a wixlib (or msm) with multiple components that >> make up a large C++ library.
