Uninstalled 3.x, installed 4.0.1 and the installation root and it's child directories were created, but 1 hour later the install dialog still says 'Creating the Wowza Streaming Engine services.' I don't see a logs folder so I'm not sure what is happening. I'm running Windows Server 2012 R2. This is obviously a busted install. What should I do now?
This is an issue we have seen, in fact it happened to me when I was installing Wowza recently on Windows 7 machine. As far as I know the problem has not been tracked down exactly.
In my experience, I found Wowza Engine listed in the Add/Remove Programs MMC, but it would not work to uninstall, Windows complained that Wowza was not installed. So I just removed the files that had been installed, then rebooted the machine, then installed again, which worked. I would also uninstall previous versions before you reboot.
