Gear Design software.
The GearWin software package is no longer available in the public domain. It is still available, for individual use, for a materials, handling and shipping fee. I do not sell or license this package for corporate or business use at this time.
The e-mail address you have listed is correct for correspondence on GearWin. The program has expanded quite a bit since you received your copy. You should obtain an update.
