I'm having trouble installing the Doom collectors edition, any help?

Hello, I recently picked up a little jem for five bucks at goodwill and I had installed it but could not get the program to run (doom collectors edition) I have windows 7, running on pentium g2120 tucked into an msi z77a-g43. I do not have it installed currently but I do remember getting an error message from windows that said I was missing something. The copyright date is 1994-2003 is Windows 7 simply too advanced to run it right off the bat or am I doing something wrong. Any help or ideas are very appreciated, thanks in advance.
