If you mean registered in GAC, here is my consideration: to be registered in GAC, an assembly must be signed with a strong name (have a public key token in it's name).

So you can try load it using Assembly.Load(string), if you got FileNotFoundException - assembly was not registered in GAC.

If got no error, but result Assembly.GetName().GetPublicKeyToken() is null or empty -- this mean you found assembly in application directory, not in GAC.
