I have an exe which keeps track of all the servers

This exe needs to run all the time and if not already started, it will start through the next CreateInstance() call made by a client.

1. Are you certain that every thread that uses any kind of COM related stuff contains a call to ::CoInitialize() or one if its equivalents?
2. Are you certain that every thread that instantiates a COM server has a message pump that will not be blocked?
3. What threading model have you registered below the server entry in the registry?
   In other words; what value is assigned to the registry value "ThreadingModel" in the registry entry HKCR\CLSID\{<your server CLSID>}\InprocServer32?
4. How is the apartment initialized from which you create the server?
   I suspect it is initialized as a multithreaded apartment.
5. Are you using proper marshalling? How?

What's more, if you want to your misunderstanding COM.

but it raises an error namely: "Type 'System.__ComObject' cannot be marshaled as an unmanaged structure; no meaningful size or offset can be computed."

I suppose if you know the size of the com object in bytes

however my guess is that is not what you want.
