Thanks for the tip, udosuk.
My puzzle may be found at

To get this puzzle running, it has to be installed on the computer where it is to run, as follows:
(1) Copy the file Huts.exe to any folder or drive on your computer.
(2) Just double-click on the file. The first time it runs, you will just be given a number. Now don't run it again! Just write the number down and exit the program.
(3) Send me a message on the Player's Forum giving me that number and I will reply giving you a second number.
(4) Now run Huts a second time. This time you will be asked for the second number. Enter it and exit.
(5) From now on the program will run without hitches.
Enjoy!
