Vmware Authorization Service

Workstation (a virtualization solution for Windows similar to Hyper-V and VirtualBox) includes VMware Workstation’s authd.exe component. In order for VMware Workstation to run and manage its internal workings, it starts a number of background services. The VMware Authorization Service uses vmware-authd to grant (or deny) permissions to launch, stop and manage virtual machines.

The VMware Authorization Service does not seem to be running. I have tried manually starting the service, but cannot get it to run. I have restarted my computer, but the problem persists.

A common error seen by Windows users when running a virtual machine on a VMware Workstation or VMware Player is “The VMware Authorization Service is not running.” This problem does not only occur on Windows 7, Windows 8, and Windows 10, but it is also present on other versions as well.
