Creating an MSI that just replaced that file with a higher version will work as long as the component guid is the same. Visual Studio setups don't expose Component guids, so I'd guess that the component guids are not the same, that would explain it.

Subject: Re: [WiX-users] Creating a "hotfix" patch for an installer built with VS By the sound of it you created an MSI that contains only your hotfixed file ? That would explain the behaviour you're seeing. You could make: Major upgrade Hotfix patch There's a minor update but it probably won't give you any advantages over a major upgrade. The easiest, if you have the original installer's source code, is to make a Major upgrade. A major upgrade automatically removes the old version and replaces it with the new one. However when you remove the new version, the old version isn't reinstalled. If you want a small update patch (.msp), this is more difficult to write and requires that the Windows Installer rules are followed more closely in the original and new installers. The patch can be removed to get back to the original installation state. There are some rules you have to follow for the different update types which are documented in the MSDN http://msdn.microsoft.com/en-us/library/aa370579%28v=VS.85%29.aspx If you're making a major upgrade then you can have Wix write the upgrade table entries for you using the MajorUpgrade element. 1. Yes you can with the Permanent attribute but it would be a bad way to fix your problem. 2. If you create one of the two update types, the files will all uninstall correctly. -----Original Message----- From: Ben Peikes [mailto:bpei...@gargoylestrategic.com] Sent: 12 July 2011 18:42 To: wix-users@lists.sourceforge.net Subject: [WiX-users] Creating a "hotfix" patch for an installer built with VS We have an old project whose installer was built using VS. I need to replace one of the files, so I want to create an installer with WIX which just installs a single file. The "hotfix" installer I've created works fine when installed, but when it gets uninstalled, it removes the file. I'd like it to replace the file that it updated when uninstalled with the original, but I'm not sure how to accomplish that. A couple of questions: 1) Is there any way to mark a <File> or <Component> such that it does not get uninstalled when you uninstall the product? 2) Is there a way to tie my wxs to another product and version such that if the other product gets uninstalled, the hotfix automatically gets uninstalled as well? ----------------------------------------------------------------------------- - AppSumo Presents a FREE Video for the SourceForge Community by Eric Ries, the creator of the Lean Startup Methodology on "Lean Startup Secrets Revealed."
