First you should check what the error code means and in your case it's "class not registered". Are you running your COM application under a different user account than VirtualBox? Is the VirtualBox.h file from the SDK matching the version of VirtualBox that is installed? We change the class GUIs when we modify its methods.
I assume you've tried tstVBoxAPIWin.cpp and given that you were able to create an IVirtualBox instance, it's most likely related to a wrong GUID. The COM API is certainly not broken because it's used internally by e.g. VBoxManage.

I'm trying to do something simple (send VM poweroff, sleep, wake, etc), but no matter what I do, I keep getting this error. I tried using the tlb file with C# first, but that resulted in a crash at runtime. Tried using C++/CLI, then that failed as well. Finally, I tried doing it via unmanaged C++ with a C++/CLI wrapper (the main app is in C#). All of these spouted the same error.
