You can download chessbase light, which is a light version of the famous chessbase database, from www.chessbase.com/
The program will allow you to read pgn or chessbase files (as fritz is made by chessbase, this means you could give your friend a database of all your games, if you've been analysing them in fritz).
This program comes with a couple of analysis engines (fritz 5.*, crafty...) so your friend can create their own database of games and analyse them. Hope this helps 🙂
