Creating an install log is you best option to debug this. Are you sure the UpgradeCode is the same between both versions? There is a sample upgrade script here http://neilsleightholm.blogspot.com/2009/01/wix-script-for-major-upgrade s.html that might help.

I am facing issue related to major upgrade in WIX. As per my understanding, major Upgrade in WIX uninstalls the previous versions and installs the newer version. In my case, the newer version is installed by WIX but the older version is not uninstalled. I have added file1.txt in version 1.0.0 of my WiX installer. In the 2nd version (1.0.1), I have removed file1.txt and added file2.txt. When I install version 1.0.0, the file1.txt gets copied at the correct location. Now, when I install version 1.0.1, the file2.txt gets copied at the desired location but the file1.txt is not removed. I was expecting the file1.txt to get removed automatically when I installed the 2nd version (1.0.1). The WIX files for both the versions has the same upgrade code. I am sure that the older version is not getting uninstalled is due to the fact that I can see multiple version of the same installable in my Add / Remove Programs. The WIX file is as below. <?xml version="1.0" encoding="UTF-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi";> <Product Id="*" UpgradeCode="393525F5-2296-4e42-A32C-07AA4E548863" Name="WixProject_Upgrade" Language="1033" Version="1.0.3" Manufacturer="Wix"> <Package InstallerVersion="200" Compressed="yes" /> <Upgrade Id="A2BFC8A4-63BE-42b3-A868-24D16D5520F8"> <UpgradeVersion Minimum="1.0.0" Maximum="1.0.3" IncludeMinimum="yes" IncludeMaximum="no" Property="UPGRADEFOUND" OnlyDetect="no" IgnoreRemoveFailure="no" /> </Upgrade> <InstallExecuteSequence> <RemoveExistingProducts After="InstallValidate"/> </InstallExecuteSequence> <Media Id="1" Cabinet="media1.cab" EmbedCab="yes" /> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLLOCATION" Name="WixProject_Upgrade"> <Component Id='file2' Guid='BD7E9E5F-52D5-4c84-9961-D5F31490971B'> <File Id='file2' Name='file2' Source='file2.txt' /> </Component> </Directory> </Directory> </Directory> <Feature Id="ProductFeature2" Title="WixProject_Upgrade2" Level="1"> <ComponentRef Id="file2"/> </Feature> </Product> </Wix> Please let me know if I am missing anything here. Thanks and Regards, Kshama
