Hi neha0123,
Could you please tell me the way you deploy the Visual Studio Add-in?
According to your description, most likely Microsoft.VisualStudio.CommandBars.dll is missing in the target machine. Does the target machine installed the Visual Studio? Can you find the dll in the target machine?
You can try to remove the dll and add it back or repair the Visual Studio.
Best Regards,
