As you say, ApplicationsLocation returning .../Start Menu/Programs seems a bit "odd". It is "surprising" that Qt does not offer anything to return Program Files etc. under Windows. Yes, these are very Windows-specific, and Qt is largely (but not totally) platform-agnostic, but still I would have guessed Qt would offer something for this. But it is what it is, and code can use environment variables or native Windows calls to get the desired path.

Don't forget to verify whether you are looking for Program Files or Program Files (x86), they are not the same place!
