I have my head spinning on this. I installed Windows 2012 server, ran updates, nothing else is installed. I installed 3CX version 12. When I open services status under 3CX, it shows first service "IIS Web Service" status blank and there is no option to start it. I see all features of 3CX, but receives errors when try changing extension. I uninstalled and re-installed app multiple times with same issue. Has anyone experienced this?
