Procedure
| In Workstation, select . If you have never imported a third-party virtual machine or virtualized a physical machine in Workstation, Workstation installs VMware vCenter Converter Standalone. After the installation is finished, you must restart the import. |
2 | Browse to the .vmc file and click Open. |
3 | Type a name for the virtual machine, type or browse to the directory for the virtual machine files, and click Import. |
