I will also tag on to this thread.
What is the status of the visual RF planner?
I see that version 8 is not supported on windows 10 from the release notes, and I am struggling to get it working. The symptom mentioned in the thread is the same for me. Try to start the application, get a small visual RF window, and the it diappears like it never existed.
I have tried emptying folders, uninstalled and whatnot.
It's a very handy application to have just to place AP's on a PDF for installation.
It's not scientificly 100% accurate, but many small installs don't want to pay for a proper WiFi survey, and are happy with a predicted model like this.
