Thank you for the reply. I have removed the OnlyDetect attribute from the UpgradeVersion element. When moving from one version to the next, I perform the following changes:
* Product Version number * Product GUID * Package GUID All other GUID's remain unchanged. Based on http://support.microsoft.com/kb/870714, I made the "later" scheduling of RemoveExistingProducts be after InstallFinalize in the InstallExecuteSequence. According to http://msdn2.microsoft.com/en-us/library/aa372038.aspx, InstallFinalize appears by default to be the last action in the InstallExecuteSequence. After implementing those described changes, the generated MSI can both upgrade an existing installation (while preserving existing data and not firing the uninstall actions) as well as load a new install; however, multiple entries are still generated in Add or Remove Programs. I have attached the updated wxs file. Have I missed something, or is there a better time to schedule the RemoveExistingProducts action? Thank you, Matthew ________________________________ From: Bob Arnson Sent: Wednesday, August 15, 2007 2:01 AM Cc: wix-users@lists.sourceforge.net Subject: Re: [WiX-users] Performing both New Installs and Upgrades with a Common MSI Matthew Sheets wrote: Major Upgrade Advantages * Can set the UpgradeVersion OnlyDetect attribute to prevent a clearing out of data during an upgrade uninstall/reinstall Issues * Creates multiple entries under Add or Remove Programs If you use OnlyDetect, you're not creating a major upgrade; that's why you have multiple entries in ARP. As the name implies, OnlyDetect doesn't remove the previous version. If you keep your component GUIDs stable and schedule RemoveExistingProducts late, then MSI won't uninstall the component and the WiX custom actions won't trigger uninstall behavior. -- sig://boB http://joyofsetup.com/
