Matrix is a small company, and it is only responsible for selling games, not making them, so try not to expect too much from it.
As for your question, try these:
(1)Install the original game, DO NOT install or copy any upgrades or cracks.
(2)Install the Return, then use "Check for Update" to update it.
(3)Install the Legend, then update. If it doesn't work(crash on start-up), then either restart your computer and try again or do (1)(2)(3) again but do not update in (2) and this is actually recommended.
If you update in (1), then it would probably crash on start-up.
