There is same question before.
http://community.wowza.com/community/questions/46957/cant-uninstall-wowza-from-windows-10.html
But it was not answered yet. But version was updated after previous question came.
So I would like to ask you have any clue or solution for it.
According to Logs… it just stops.

I’m looking into this for you with tech support to see if they can answer without needing a support ticket.
Is it possible that the Engine services were still running when you tried to uninstall it?
System services start automatically when you start the computer and remain on until you turn them off. By default, Wowza Streaming Engine server software and Streaming Engine Manager install as system services, which means you’re running an active instance of Wowza Streaming Engine from the moment of install and any time the host computer is on.

Can you make sure the services are truly stopped and then try to uninstall it again? Please let me know.
