With the launch of any of the 5 Heroes games (original, expansions, unofficial expansions).

This is a bug with Windows XP SP3, because the patches won't install, saying that the game is either not installed or installed incorrectly!

Well, based on my perversions experiments with Windows, it doesn't depend on the SP. And your error occurs quite often in pirated versions.
