Issue/Introduction

  • Powering on a Windows virtual machine fails with an error message:
    The VMware Authorization Service is not running.

Cause

This issue occurs when the VMware Authorization service is not running or when the service does not have Administrator rights.

Resolution

Resolution of the Error: "The VMware Authorization Service is not running":

To resolve this issue, follow the steps below:

 

 

Process to Start the VMware Authorization Service or to check Whether it is Running:

  1. Login to the Windows operating system as Administrator.
  2. Click Start and enter Run. If you are unable to find the Run option, refer to Microsoft article What happened to the Run command?
  3. Enter services.msc and click OK.
  4. Scroll down the list and locate the VMware Authorization service.
  5. Click Start the service, if the service is already not showing a status of Started.

    Note: The VMware Authorization service depends on the Windows Management Instrumentation service. This service must be running as well. If the VMware Authorization service does not start, or starts and then stops, locate and start the Windows Management Instrumentation service.
**If the VMware Authorization service is already showing a status of Started, then the service does not have Administrator rights.
 

Note: This issue typically occurs with Windows Vista hosts, but can occur with other versions of Windows operating systems too.

 

Process to Provide Administrator Rights to the VMware Authorization Service:

  1. If using Windows Vista or later, disable User Account Control (UAC).

    Notes:
  2. Add Administrator rights to the Windows user account that runs the VMware Authorization service.

    Notes:
    • To ensure that you have Administrator permissions in Windows XP, follow the instructions in Step 1 of Microsoft's Knowledge Base article 951244.
    • To log on as an administrator in Windows Vista, see the Microsoft article Change a user's account type.
    • To log on as an administrator in Windows 7, see the Microsoft article How do I log on as an administrator?
  3. Uninstall VMware Workstation.
  4. Reboot the host machine and log in as a local administrator (not as a domain administrator).
  5. Reinstall VMware Workstation.
