NOTE: If you are trying to fix a problem with multiple visual micro menu or tool bar items then please click "Tools>Reset User Interface". If that fails add the /resetaddin command below to your Visual Studio or Atmel Studio program short-cut. If the problem persists please report it in the forum 
After uninstalling Visual Micro using windows control panel (or by running the installer again and clicking 'Remove'), the Visual Studio or Atmel Studio Ide might still contain Visual Micro menu items and tool bar buttons
Run the Atmel or Visual Studio windows shortcut with the following switch appended with a space after the .exe name. After running the ide once, close and remove the /resetaddin command from the shortcut.
Visual Studio: [path to devenv.exe] /resetaddin Visual.Micro.Visual.Studio.Arduino.Helper
Atmel Studio: [path to atmelstudio.exe] /resetaddin Visual.Micro.Visual.Studio.Arduino.Helper
