Installing a new Windows service version

I have a Windows Service written in C#. I have a setup project for the service that installs the service without issue. The challenge comes when I want to deploy a new version of the service. I have set the RemovePreviousVersions property of the project to true, but I still get an error message at the end of the installation telling me that, "The specified service already exists". In Custom Actions, the primary output for the service assembly is listed under Install, Commit, Rollback and Uninstall. Does this deployment project feature not work for services? Is there something I can do to get the installer to uninstall a previous version if the service already exists? Thanks.

In the onBefore Install event you can write a code that will uninstall the service so that the install might be successfull
