"All Windows 10 editions (both LTSB and non-LTSB) continue to have a
calc.exe, which however is just a stub that launches (via ShellExecute)
the handler that is associated with the 'calculator:' pseudo-protocol."

So you need to install a handler for the protocol. That means having to
get one from the MS Store. Or ...
