Key each executable to the hard drive serial number. That way the executable
will only work on PCs with that particular serial number.

You can do it one of two ways: build a custom executable for each customer
after you get the serial number of the drive to which it will be installed,
or use an ini file (or registry or whatever) that uses a format like this:

----License File------------------------------------------
-- Do not tamper with this file or your license will be --
-- broken and you will have to purchase another copy.   --
----------------------------------------------------------

The number after the bracket is the licensed PC serial number. The number
after the pound sign is a checksum of the contents of the license file.
Without the license file, the program doesn't work. If the person tries
to tamper with the license file, the checksum will not match and the
program won't work.

It has worked for me for 15 years.
