What's the correct way to reference the DLL in your visual studio project? I've tried it on two different system and I keep getting:
"Unable to load DLL 'acccore.dll': The specified module could not be found."
This happens also with the unmodified samples included in the SDK.

You will need to copy all
You will need to copy all the DLLs from the sdk release folder and move them into your project, just as xzanidev explains.
