Best method would be to remove it from the Programs and features under the control panel. Once uninstalled go to your Local disc C: drive and delete the Torchmate CAD folder. Run the Torchmate CAD installer again. When prompted plug in your Security Dongle, next, next full install. After the program is reinstalled you will want to go to Machine/Machining defaults and check to make sure your on the appropriate "Selected Driver" If your running Torchmate 3 or 4 software you will want to be on the Torch mate Dual Tool Driver. If your running Accumove you need to select Accumove Imperial then apply then close. Also to be on the safe side go to Options, Torchmate Setup, General Preferences, make sure that your units are set to inches, and your speed units set to in/min then select ok. Reinstall your fonts from their as well if you need to.
