Resident evil 3 running help!!!

Hello thanks for your time in reading this message. I just finished downloading Resident evil 3 to my download file, but when I clicked it it said that I need to open the game with something it also says it a 72 file. Not really sure what that means I am a amateur when it comes to computers. Overall what do I need to do to play this game on my laptop?

Open it using WinRAR or 7-zip.
and then Extract it.

If that is all then thank you I shall see if it works.
