How to prevent a windows user from being removed and created during a patch.

Question

I have a project that uses the wix extension WixUtilExtension to create a user for our windows services. When I patch the installation (using an .msp), the custom actions RemoveUser and CreateUser are executed.

I don't want these wix extension created custom actions to run during a patch.

I can add a condition directly to the custom action (ConfigureUsers) in the InstallExecuteSequence table of the msi to prevent this, but have not found a way to handle this in wix.

Using wix, how can I prevent RemoveUser and CreateUser from being executed during a patch?

<util:Group Id="LocalAdministrators" Name="Administrators"/>
<DirectoryRef Id="INSTALLLOCATION" DiskId="1">   
  <Component Id="CreateServiceAccountUser" Guid="{614550A7-C766-4B5D-9BF9-233D07EB3B69}">

    <util:User  Id="ServiceAccountUser"   CanNotChangePassword="yes" CreateUser="yes" Disabled="no" FailIfExists="no" LogonAsService="yes" Name="TestUser" Password="testuserpw" PasswordExpired="no" PasswordNeverExpires="yes" RemoveOnUninstall="yes" UpdateIfExists="yes">
      <util:GroupRef Id="LocalAdministrators"/>
    </util:User>

    <RegistryKey Root="HKMU" Key="Software\AMT\WebBrix">
      <RegistryValue Name="CreateServiceAccountUser" Value="Common" Type="string" KeyPath="yes" />
    </RegistryKey>

  </Component>
</DirectoryRef>

You can do that in wix,

<InstallExecuteSequence>
    <Custom Action='ConfigureUsers' After='InstallFinalize'>NOT Installed</Custom>
</InstallExecuteSequence>

here are some more conditions

1. Action run only during Install Condition: NOT Installed AND NOT PATCH
2. Action only runs during removal of MSI Condition: REMOVE
3. Action runs during Install and repair Condition: NOT REMOVE
4. Action runs during Install and remove Condition: There must be no condition
5. Action calls EXE installed by MSI Condition:NOT Installed AND NOT PATCH
6. Run on initial installation only: NOT Installed
7. Run on initial install or when repair is selected. NOT Installed OR MaintenanceMode="Modify"
8. Run when being uninstalled from command line or add / remove menu. REMOVE~="All" OR MaintenanceMode="Remove"
