This issue occurs if the vstor2 service has failed to start.
Resolution
To workaround this issue:
Query the vstor2 service to determine its current state. Open the command prompt and run the following command:
sc query vstor2-mntapi10-shared
If the output shows as not started you can manually start the service with this command:
net start vstor2-mntapi10-shared
If the query shows the service is already started, a reboot of the OS may address the issue.
Note: If the query shows the service is unavailable, it may be necessary to use the Repair installation option available with the VMware vCenter Converter software installation media to resolve the issue.
