I installed WowzaStreamingEngine-4.0.6 but I couldn't able to start the service.
It's throwing a error message as,
'Windows could not start the Wowza Streaming Engine 4.0.6 service on Local Computer.
The service did not return an error. This could be an internal Windows error or an internal service error.
If the problem persists, contact your system administrator.'

I'm using windows 7 ultimate and its 64 bit OS. I installed java version "1.7.0_67" and followed the steps in the link,
I tried many times uninstall and reinstalling the java and wowza server but nopthing worked for me.
Can you please help me on this?
