Forticlient Service Scheduler does not start on Windows 10 login

We have just started using the Forticlient AV as our antivirus. We also use a Forticlient EMS to create the installers for our environment. At first, when it was installed, the Forticlient Service Scheduler service was starting but now I have several machines that are not starting the service even though it is set for Automatic. Anyone have any ideas on why and how to fix this?

Thanks!
