The Services window will come on screen. Look out for VMware Workstation Server from the list of services
Click on Start the service
Verify if the service is started
Also make sure the service starts automatically from next time to avoid these steps in future. Right click the service and open the properties dialog box
Select Automatic from the drop down option and also verify the service is started as shown below and click on OK to apply the setting
