Download Fritz 8 (Windows)

The game should work fine on modern systems, tested on Windows 10. If the installation doesn't start - run Setup.exe in compatibility mode with old Windows, like Windows 98, and as administrator. If the installed game doesn't start - run it in compatibility mode with old Windows OS, like Windows XP.

Second CD of Fritz 8 is Talk CD, it includes audio lessons, you must have that disc in virtual drive if you want to play with audio lessons. The game was using protection with Read Errors, so if the game doesn't start - use the NoCD, you'd be able to play the game but without audio lessons

Notes:

• Looks like that the online matches are still working, so if you have a working serial key, you can play against live players. It seems that Russian version of the game may have issues with connection to multiplayer game, according to comments in this thread
