Yup.

However, actually searching could be horribly slow. The best strategy
(in my view) is to follow through the registry entry chain to work out
how (or if, or course) the system would try to open an Excel data file.

Then look to see if excel actually exists in the location that gives
you.

It's possible that the result isn't actually Excel, merely whatever the
system has been told to use on Excel files.
