How to Troubleshoot: VMware Internal Error

From time to time I need to access a virtual machine using VMware Workstation, but unfortunately, it decides it doesn’t want to work today and sends me a useless “Internal Error” message. Thanks for that, VMware; very informative. I guess I should at least be thankful that it wasn’t an “unforeseen error,” but then again, I guess they expected that, so back to square one.

Since this has happened to me several times over the years, I thought maybe I should document it somewhere to save some poor soul from panic. The more documentation, the easier it is to find; it would also help me, since my memory is like, well, you know, one of those things. Anyway, the first time I got this error was 30 minutes before the session started, and a two-word error doesn’t give you much reason to go on.

First, let’s take a detailed look at the causes of this error and then mention solutions you can apply to fix the problem.

What is the cause of the internal VMware error?

VMware Authorization Service failed to start: As mentioned earlier, the main reason for this problem is that the VMware Authorization Service cannot be started in Windows. This error can occur if the Authorization Service is not running correctly in Windows.

Lack of administrative rights for VMware Authorization Service: VMware Authorization Service requires VMware administrative rights to start and run virtual machines. Therefore, if you run the service without administrative rights on your computer, you will get this error message.

Aggressive antivirus software: If antivirus software configured for aggressive mode is installed on your computer, the antivirus software may not even allow VMware virtual machines to start. Some anti-virus or anti-masking software can also prevent virtual machines from running on your system. This error can also be caused by anti-virus or anti-masking software.

Damaged VMware desktop or disk: If the VMware desktop is damaged, this error may occur.

Fix-game.exe virus: There is a known virus that prevents VMware from running virtual machines. It is fixed game.exe, and you can find it in Task Manager when it is running.

How to resolve the VMware Internal error?

Launch the VMware authorization service with administrator privileges

  1. Type services.MSC in the startup window. (To open the startup window, press the Windows + R key).
  2. Then find the VMware authorization service in the list of services.
  3. Double-click the service and click Run.
  4. Also, make sure that the startup type is set to Automatic.
  5. Now check the virtual machine in Vmware again.
  6. Hopefully, everything is working correctly now if the error was caused by a VMware authorization service failure.

Reinstall Vmware using the restore option

For some users, the problem was solved by reinstalling VMware using the restore option in Control Panel. To reinstall Vmware using the restore option, follow these steps.

  1. Go to Control Panel -> Applications and Features -> find Vmware in the list of programs and right-click it, then select Repair.
  2. If your VMware was corrupted or something similar and the error was caused by this, then fixing Vmware will most likely solve the problem.

Running VMware as an administrator

VMware’s authorization process is used because it allows non-administrators to create virtual machines.

Now, if you run VMware with administrator privileges, this service does not need to be run to create a virtual machine because you are the administrator in this case. So, if solution 1 does not fix the error, try running VMware as an administrator.

  1. To do this, simply open Vmware Workstation or VMware Player with administrator privileges.
  2. You can run the application in Windows with administrator privileges by right-clicking on it and selecting “Run as administrator”.

Frequently Asked Questions

Failed to start the virtual machine. If the Enable Power on the virtual machine after recovery option is selected, VMware attempts to power on the recovered virtual machine before disabling replication. Deselect the Power on the virtual machine after recovery option when starting the recovery.

  1. Go to services.
  2. Then find the Vmware Authorization service in the list of services.
  3. Double-click the service and click Run.
  4. Also, make sure that the Startup Type is set to Automatic.
  5. Now check the virtual machine in Vmware again.

Services provided by a virtual machine can become unresponsive or unavailable for a variety of reasons, including problems with applications or the guest operating system on the virtual machine, problems with the virtual machine monitor or virtual devices, resource conflicts on the host, or problems with underlying storage.

Shut down the virtual machine, then restart the host machine. In Workstation, go to VM -> Settings -> Network Adapters. Make sure that the network adapter is connected (i.e., connected and Connect when powered on). Make sure the network adapter is set to NAT or Bridged and not Host-Only.
