I want to remove/uninstall pre-installed lower version MSI before/with installation of a higher version of MSI. My product codes are always unique and upgrade codes are always the same.
(I don't want to allow downgrading installation.)
But when I install a higher product version MSI, it gets installed but the add/remove program entries for both new installed and previously installed MSIs still exist. How to overcome this issue ? Following is my code
<Product Id="*" Name="MyApp" Language="1033" Version="1.11.1111" UpgradeCode="00000000-8030-4B76-8F3A-8B8BB1000000">
<Package InstallerVersion="200" Compressed="yes" Platform="x86" />
<MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." AllowDowngrades="no" Schedule="afterInstallInitialize"/>
<Upgrade Id="{00000000-8030-4B76-8F3A-8B8BB1000000}">
<UpgradeVersion OnlyDetect="no" Maximum="99.0.0.0" Property="PREVIOUSVERSIONSINSTALLED" IncludeMaximum="no"/>
<UpgradeVersion OnlyDetect="yes" Minimum="1.0.0.0" Property="NEWERPRODUCTFOUND" IncludeMinimum="no"/>
</Upgrade>
