[wix-users] RemoveRegistryKey in a dual-scope MSI

[Dzmitry Razhanski]

Hello,

Probably you need to use these attributes for your component:
	 Permanent="yes" NeverOverwrite="yes"
And remove it manually by condition.


Best regards,
	Dzmitry Razhanski.

correction (I'd copypasted an older version, sorry), my code includes CreateFolder like this, otherwise it errors.

        <DirectoryRef Id='TARGETDIR'>
            <Component Id="AlanRemoveRegHKLM"
Guid="3A735F83-591B-4E25-B1CB-1498A6770873" Win64='$(var.V_WIN64)'>
                <Condition> ( not UPGRADINGPRODUCTCODE ) and ALLUSERS </Condition>
                <CreateFolder></CreateFolder>
                <RemoveRegistryKey Root="HKLM" Key="Software\Myapp\Settings"
Action="removeOnUninstall" />
            </Component>
<!--Perhaps the above AlanRemoveRegHKLM component is redundant .. haven't checked -->
            <Component Id="AlanRemoveRegHKCU"
Guid="4950E1DD-A5FB-42D6-A872-A74230ED8841" Win64='$(var.V_WIN64)'>
                <Condition> ( not UPGRADINGPRODUCTCODE ) and ( not ALLUSERS )</Condition>
                <CreateFolder></CreateFolder>
                <RemoveRegistryKey Root="HKMU" Key="Software\Myapp\Settings"
Action="removeOnUninstall" />
            </Component>
        </DirectoryRef>


The problem remains the same: registry key is deleted during upgrade, but we need it deleted only at final uninstall.

thanks
Alan
