What is Transport (VMDB) Error?

Fix Transport (VMDB) error -14: Pipe connection has been broken

If you see Transport (VMDB) error -14 in VMWare Workstation and the Pipe connection has been broken, follow the steps mentioned below to resolve the issue.

1. Resolve Mismatch Version Error
2. Disable Hyper-V

The pipe connection breaks when there is a mismatch with the vmx86 driver. When launching the virtual machine, the following error message appears and only after clicking the OK button, do victims see “Pipe connection has been broken”.

Version mismatch with vmx86 driver.

If you are riding the same boat, follow the steps mentioned below to resolve the issue.

Finally, open VMWare and check if the issue is resolved.

2] Disable Hyper-V

Hyper-V is a Microsoft Hypervisor technology that allows users to create Virtual machines in Microsoft’s own Hyper-V Manager. If the feature is left enabled, it will conflict with VMWare services and cause issues. In this case, we can disable the feature from Control Panel and let VMWare services flourish. To do the same, follow the steps given below.

• Open Control Panel from the Start Menu.
• Change the View by to Large icons.
• Then click on Programs and Features.
• Now click on Turn Windows features on or off.
• Look for Hyper-V and untick the box associated with it.

After disabling Hyper-V, check if the issue is resolved.

3] Take a backup and remove the VM

If you still get the error message, take a backup and remove the Virtual Machine because VMDB errors occur when the machine is corrupted. So, go ahead and take a backup of the VM, remove it, create a new one, restore all the backups, and check if the issue persists.

4] Reinstall VMWare Workstation or Player

If nothing worked, your last resort is reinstalling the VMWare Workstation application installed on your computer. It is possible that the copy of the app installed on your computer is corrupted. That is why we will uninstall the application and reinstall it. Follow the instructions given below to uninstall VMWare Workstation from your computer.

• Open Settings.
• Go to Apps > Installed apps or Apps & Features.
• Look for VMWare Workstation.
  • Windows 11: Click on the three dots and select Uninstall.
  • Windows 10: Select the app and click on Uninstall.
• Click on Uninstall to confirm your action.

Once you have removed VMWare, go to vmware.com, and download a fresh copy of the same. After downloading the application, go to the Download folder, launch the installer, and follow the on-screen instructions to complete the installation process.
