Cant get Ignition Gateway to run on a Windows Server

I cant get Ignition to run in my Browser. I changed the port from 8088 to 80 and now it brings up IIS. How do get around this

You’ll have to disable IIS, change the port it runs on, or leave Ignition on port 8088.

You can’t have both pieces of software trying to use port 80.

Thanks you.
