Hello,

I am trying to launch a game that was created with SlimDX. I should say that I am not a developer. I am getting the following error when launching the game:

SlimDX.DirectInput.DirectInputException: REGDB_E_CLASSNOTREG: Class not
registered (-2147221164)
at SlimDX.Result.Throw[T](Object dataKey, Object dataValue)
at SlimDX.Result.Record[T](Int32 hr, Boolean failed, Object dataKey, Object
dataValue)
at SlimDX.DirectInput.Device..ctor(DirectInput directInput, Guid subsystem)
at SlimDX.DirectInput.Mouse..ctor(DirectInput directInput)
at RR.GameEngine.InitializeInput()
at RR.GameEngine.Initialize()
at RR.GameEngine.Run()
at RR.main.main()

This is a specialized game designed for blind users. I have contacted the developer and he is unsure what is causing this error. Since I am blind, I do not have a mouse connected. Is this error resulting from not having a mouse on the system?

The system is a Windows 8.1 desktop machine.

Looking at the stack trace it does seem that the error is occuring when the program is trying to initialize the mouse. Do you have a mouse you can borrow to see if that is the issue as it looks like it is to me.

I'll track one down. Not like they're expensive if I need to go buy one.
