The ugly middle management?
Obviously, it seems to be between executive management and middle management where you can find the roadblocks. Senior managers, stating "This is a nice idea. Why don't you go ahead and work with it? And please, don't bother me too much with this stuff in the future!"
What is this supposed to mean? Is it rejection? Not really. Is it support? Hardly. In other words, it is worth nothing, but you are decoupled from executive management.
