How do I get rid of the trial banner generated by LF Fortran?

[R. T. (Fortran Man)]

I've installed LF Fortran and it returns a trial banner when I run the compiler. How do I get rid of the trial banner?

[Lahey Support]

By default, the Lahey/Fujitsu Fortran v7.X product is installed with licenses set up to expire after an evaluation period. To continue using a purchased product, the licenses must be activated.

Activation can be done automatically using an internet connection or manually by contacting Lahey.

For more detail see Product License Activation in the installation guide included with the product. This information is also available in the online help within Visual Studio and at http://www.lahey.com/docs/lfprohelp/f95gsactivation.htm.
