Different apparent cause, but same symptom, for others who find there way to this post.

I ran an application that had "always worked", and after various (not logged since I was not expecting issues) combinations of running it via remote desktop or locally, logging in and out, and replacing it with a recompiled but otherwise identical version with a different version number I got the same "Another application has already registered this URL ...blah, blah".

Apparently (?) the registration was specific to the instance that ran, and persisted across shutdowns of that application. (?) In any case the old Windows adage, "when in doubt reboot" took care of it. With no changes to the app itself it then ran with no complaints. It may be that de-registering, etc., would also have worked. This was under Windows 10 - I have never seen this with earlier versions of Windows.
