MajorUpgrade element is scheduled after install finalize in our product's MSI:
<MajorUpgrade Schedule="afterInstallFinalize" AllowSameVersionUpgrades="yes" DowngradeErrorMessage="!(loc.NewerVersionInstalled)" IgnoreRemoveFailure="no"/>
There are some folders written by app at runtime that we want to keep on upgrade and only remove on uninstall initiated from Add/Remove programs. So we use this condition: (NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL").
<DirectoryRef Id="TARGETDIR">
...
<Directory Id="LocalAppDataFolder"
xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">
<Component Id="CreatePrivateMyAppFolder" Guid="FA1F4375-71DA-4E61-9A02-BE7FD2D4C87D">
<RegistryValue Root="HKCU" Key="Software\Company\Product" Name="PrivateFolderMyApp" Type="string" Value="[PrivateDataMyApp]" KeyPath="yes"/>
</Component>
<Component Id="RemoveLocalAppDataMyAppUninstall" Guid="*" Transitive="yes">
<Condition><![CDATA[(NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL")]]></Condition>
<RegistryValue Root="HKCU" Key="Software\Company\Product" Name="PrivateFolderMyApp" Type="string" Value="[PrivateDataMyApp]" KeyPath="yes"/>
<util:RemoveFolderEx On="uninstall" Property="PRIVATEMYAPPFOLDER"/>
</Component>
<Directory></Directory>
...
</Directory>
</DirectoryRef>
I need to change the MajorUpgrade schedule from afterInstallFinalize to afterInstallInitialize for some new requirements. I install version 1 with new schedule. Then install versions 2. However during uninstall sequence of version 2, folders written by runtime are being removed.
From logs, both UPGRADINGPRODUCTCODE and REMOVE properties are set for the uninstall part. Based on that the condition (NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL") should evaluate to false for the component RemoveLocalAppDataMyAppUninstall.

Any help in understanding why the condition is being applied during uninstall will be appreciated.
Component conditions only affect install and, with the transitive bit set, reinstall. Uninstall isn't affected.
