WiX Windows service install failure

Question

I am trying to use WiX for my service installation. This tries to install my service but eventually fails. Do you have any idea? My service should use a local user account. This account was added as "users which can run window services".

Account="LocalSystem"

instead of

Account=".\\MySvcUser"
