How do I solve the license error when using XlsIO in Windows Service?

The following error may occur:
Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.
This often indicates that the license file is not embedded in the application. Please follow the steps given below:
- Include the license file in the project as an Embedded Resource.
- Now recompile the application; it should work in the Windows service.
