Well, not sure ours was the best solution, but what we did is a custom action that literally moves all registry entries related to per-user package to per-machine. That means from HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\SID-OF-USER to UserData\S-1-5-18 (latter stores per-machine installations).
We decided to go this way because: 1. It is not possible to uninstall another MSI from custom action since Windows Installer doesn't allow concurrent installations 2. Per-user installation could have been installed with different user than the one performing upgrade - this way MSI will not "see" that there is something installed. At least we saw this behavior from our investigations. Today, I wouldn't recommend going this way - it is too buggy. Instead I would create a custom action that detects such per-user installation and asks user to uninstall first. -----Original Message----- From: Derek Wickern [mailto:dwick...@gmail.com] Sent: Wednesday, November 28, 2012 02:51 To: wix-users@lists.sourceforge.net Subject: [WiX-users] WiX 3.6 upgrading perUser to perMachine I need to upgrade a package which was unfortunately created with per-user scope. It's installing to ProgramFiles. I understand that MSI can't upgrade my perUser to perMachine. I have some ideas: 1. Automatically uninstall the per-user package (custom action?) 2. Install the per-machine package right on top of the per-user package 3. Detect the scope of the original package and upgrade to the same scope. Otherwise default to perMachine. I just upgraded my project to WiX 3.6 and I'm using burn to create a boostrapper. I'm hoping that gives me more options. What's the best solution here? ------------------------------------------------------------------------------ Keep yourself connected to Go Parallel: INSIGHTS What's next for parallel hardware, programming and related areas?
