I need help loading game

[Atticus Rex]

Ok, I am not computer savvy at all. But, I miss this game so much. And I just found this so I am super excited to load it. I'm having some trouble however. I've followed the instructions and when I attempt to run "matrix.exe", I get the error "MFC71.DLL" is missing from your computer. But, if I scroll down just a bit, I see it sitting in the same folder. Any suggestions?

Also, as a side note, I do not have the original game on this computer. It's been several computers since I had the game.
