WiX Windows service install failure - windows

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".

Answer 1

Try
Account="LocalSystem"
instead of
Account=".\MySvcUser"
