Have you configured the game with the Sound setup program?

Here are two attachments: one is for the game start up when I click Harvest and a Dos-like window opens (harvest start.doc) and the other is when I try to open sound setup (sound start.doc).

The setup program doesn't detect a compatible digital device in your system, or you haven't selected your device yet. Which sound card do you have? It should offer hardware or software compatibility with one of the listed in "Select Digital" option in order for the game to work.

If "Auto Detect" doesn't work on you, try to manually enter the sound card configuration in "Select Digital". Those settings must be the same as in the control panel entry for Sound Blaster if you have an ISA SB 1.0, 1.5, 2.0, Pro, 16, AWE32 or AWE64, or in the control panel entry for Legacy Device if you have an Ensoniq AudioPCI, SB PCI 64, PCI 128, PCI 512, Live! or Aureal Vortex 1/2 (Control Panel -> System -> Device Manager -> Sound, Video and Game Controllers). If your sound card is other than those above, I don't know what kind of Sound Blaster compatibility or emulation it can support.

Thanks for the tip. That did the trick.
