That is supported by Windows Installer and shouldn't be happening if your MSI is setup correctly even in Installshield. For a major upgrade you need to change the Package code, Product code and version and leave the Upgrade code the same.
WiX 3.5 makes this easy to setup http://wix.sourceforge.net/manual-wix3/major_upgrade.htm, http://www.joyofsetup.com/2010/01/16/major-upgrades-now-easier-than-ever/ Here is the setup for v3 http://neilsleightholm.blogspot.co.uk/2009/01/wix-script-for-major-upgrades.html Neil -----Original Message----- From: Ian Brooke [mailto:ianbro...@hotmail.com] Sent: 08 May 2012 01:38 To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Add/remove Programs I hope you don't mind this slightly unusual question! We have a product currently installed by Installshield (Express 2012) which we are considering switching to WiX but don't really want to spend the time doing that if it doesn't solve our problem. What I really need to determine is if this is standard Windows Installer behaviour or, if I can stop it happening by switching to WiX. Here's the problem - We are creating an msi embedded exe which is intended to either upgrade an existing version if one exists on the target computer otherwise do a full install. The upgrade has a new Product Code but the existing Upgrade Code. Both the upgrade and install appear to work fine, except.... Problem 1. After an upgrade if we check Add/Remove Programs there are 2 entries, one for the old version and one for the new one. Problem 2. After an upgrade I can use the old version uninstall entry and that works Ok and leaves the new version Ok. However, if I then uninstall the new version it leaves an empty application folder (which was originally created by the old version install) under Program Files(x86). I'd really like to stop both of these happening. Thanks for any advise. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
