Class not registered errors with sharpDX

Question

I'm trying some sharpDX examples and I;m getting this "Class not registered". I figure from the error its an os thing but I dont see why? I have installed the DX run-time as mentioned n the sharpDX page and I'm using windows7 64. This is a win32 app though.

error

An unhandled exception of type 'SharpDX.SharpDXException' occurred in SharpDX.dll

Additional information: HRESULT: [0x80040154], Module: [SharpDX.DirectInput], ApiCode: [DIERR_DEVICENOTREG/DeviceNotRegistered], Message: Class not registered

Code: joystickState = new JoystickState(); Guid foundDevice = new Guid(); joystick = new Joystick(directInput, foundDevice);

Answer 1

You are not using correctly the API. The Guid should match a registered DirectInput Joystick Guid. Check more carefully the sample JoystickApp that is dealing exactly with this.
