Installing two gateways

I am looking for some advice on installing Ignition Edge on my computer and running it alongside with Standard, which I already have installed. I found steps online to change the wrapper.name to something unique, as well as changed the port, ssl port, and metrossl port for my Edge install but I still get the same error message in my command prompt.

"Unable to to install - The specified service already exists (0x431)"

Anybody experience this or know what else I need to change to get the install to happen?

My goal is to have Edge be my backup in case of a comm failure through the Local Client Feedback, so I know having both installed on one device is possible.

Docker makes life a lot easier for running multiple on the same computer.
