Then you have the shortcut.
Or you open the toawIII folder, left click the exe and hold and move it out of the folder on your desktop i.e.
Right click on the shortcut icon and go to properties. In the line 'target' you can add a command line in double quotes ("nosound").
Hope this helps and works. See also the attachment; it's from Acow for the toawlog feature, but will be the same for Toaw III and nosound.. It's all in german but the displays will be the same (it's from win98 SE).
