There is no WHDLoad install for it, probably because it's well-behaved and already comes with an HD installer. If you're looking for a WHDLoad installer just check the official whdload.de, if you can't find it there then one has obviously never been made.
You can find complete and downloadable installs of other games on whdownload.com, and there are cracked versions of Sim City 2000 in the TOSEC which you can download from f.ex planetemu.net.
