Estou usando a ferramenta wix 3.11 para criar um msi que instala um serviço. O instalador executa uma ação personalizada e retorna vars ao wix para gravar no registro (HKLM). O serviço inicia e tenta ler o registro, mas não pode ser feito e falha. Se eu escrevi o registro manualmente, o instalador funciona perfeitamente.

Mensagem de erro dos logs do msi:

Product: Installer-- Error 1920. Service 'XPTO Server' (xpto_server) failed to start.  Verify that you have sufficient privileges to start system services.

Meu XML Wix:

<Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" InstallPrivileges="elevated" />
...
<ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER">
  <Component Id="CMP_RegistryEntries" Guid="xxxxxxxxx" >
    <RegistryKey Root="HKLM" Key="SOFTWARE\XPTOInc\XPTO\XPTOServer\BetaVersion">
      <RegistryValue Name="token" Action="write" Value="[TOKEN]" Type="string" KeyPath="yes" />
      <RegistryValue Name="[IDENTIFIER_TYPE]" Action="write" Value="[INSTALLEDID]" Type="string" />
      <RegistryValue Name="installDir" Action="write" Value="[INSTALLFOLDER]" Type="string" />
    </RegistryKey>
  </Component>
  <Component Id="CMP_XPTOServerEXE" Guid="xxxxxx">
    <File Id="FILE_XPTOServerEXE" Name="xpto-server.exe" Source="Work\xpto-server.exe" KeyPath="yes" />
    <ServiceInstall Id="InstallExporterService" Name="xpto_server" DisplayName="XPTO Server" Description="Read data from Registry and do simple stuff" ErrorControl="normal" Start="auto" Type="ownProcess" />
    <ServiceControl Id="ServiceStateControl" Name="xpto_server" Remove="uninstall" Start="install" Stop="both" />
  </Component>
</ComponentGroup>

EDIT: Quando eu escrevi manualmente os vars no Registro, o serviço é instalado com o msi pkg ou em execução com sc.exe

EDIT 2: Aqui segue o log onde define o registro e, em seguida, serviço estrela
