Old versions of itunes not detected.

[ghost]

A windows pc with itunes 12.5 installed does not have it detected properly (sometimes detecting, usually not), it also shows skype and spotify as installed though that is only because they were recently uninstalled.

Testing with a newer version installed (12.10) detects it properly.

I mean this is just a POC maybe we add a disclaimer like: "app not detected/app detected incorrectly?" and just list possible exceptions and reasons why it may not work for them

The external URL scheme might be different for 12.5 and 12.10
