If you have a bootstrapper that is marked in Vista as "requiresElevation" the entire MSI will be elevated since the MSI APIs will be called from that elevated context. There are several negative issues that can result from that (you may discover that the reason you need elevation causes repair or even uninstallation failures).
The series of blogs with the table of contents on this post (http://blogs.msdn.com/rflaming/archive/2006/10/01/uac-in-msi-notes-answers- to-questions-in-comments-from-earlier-blog-posts.aspx) is an excellent guide to understanding Rob's statement. I especially like this (http://blogs.msdn.com/rflaming/archive/2006/09/21/765586.aspx) post in the series to see what parts of the install run from the POV of the "installing user" and from LocalSystem. Note that the "installing user" will either be elevated or not depending on the context of whomever is calling the APIs. Note also that msiexec.exe runs "asInvoker", so it won't elevate by itself. This blog post (http://blogs.msdn.com/astebner/archive/2006/12/13/some-useful-things-i-have -learned-about-windows-installer-and-uac.aspx) is a good place to see how to adjust WiX authoring to fix these issues. -----Original Message----- From: Roy Chastain [mailto:r...@roychastain.org] Sent: Friday, September 11, 2009 3:57 AM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Please explain - "ran your entire MSI elevated" Rob Mensching just made the reply below and I don't want to hi-jack that conversation, but I would like an explanation of that that statement. Do we have control over what part of the install is elevated and if so, how? ---------------------------------------------------------------------- Roy Chastain -----Original Message----- From: Rob Mensching [mailto:r...@wixtoolset.org] Sent: Friday, September 11, 2009 06:40 To: General discussion for Windows Installer XML toolset.
