1. You can build MSIs with WiX that don't require running the setup as administrator. Nothing that can be done outside of Windows Installer without elevation requires elevation in Windows Installer to also do.
2. Windows Installer has no built-in support for detecting/removing non-MSI packages. However, if you know how to find/remove your SetupSpecialist package (the Uninstall key, perhaps?) then you can detect presence and automate removal as part of your upgrade (does the old installer allow "silent" removal?) You may have trouble detecting/removing things installed by other than the current user, however, but that is due to the nature of how Windows treats user accounts/profiles, not do to any inherent limitation in Windows Installer itself. -----Original Message----- From: Lukas Haase [mailto:lukasha...@gmx.at] Sent: Wednesday, July 21, 2010 1:20 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Upgrading from other setup program to WiX/MSI Hi, Today I began creating my first WiX project. Until now I used SetupSpecialist but as I am facing serious problems with it I want to use WiX in future. This is my first big question: On clients' computers there will be an old instance of my program (with SetupSpecialist) installed. Even worse: My new version requires the setup to be run as administrator. However, the old versions might be installed as normal users. What is the best way to handle this situation? Thank you.
