Examples on building foreign resources and run-time systems under

How to Re-Enter License Information under Windows
The SICStus development system
spwin.exe) will prompt for license information if the
license entered during installation was invalid or has expired.
Note: prior to SICStus Prolog 4.6.0 you need to use
