Because Ignition runs as a service I don't think it's possible for code running in gateway scope (tags, perspective) to open a GUI window even with "interact with desktop" enabled.

> My understanding is that this isn’t possible since Windows 7. Even when you change the user the service runs as and check “allow interaction with desktop” it still runs in session 0 where it will not be seen. These changes simply allow the process to be started without failing so that legacy applications relying on the behavior don’t crash.
