The application “OctoMouse” can’t be opened

[bland328]

When attempting to launch OctoMouse v1.7 under Catalina 10.15.4, I get only a dialog stating:

The application “OctoMouse” can’t be opened.

There's also a help button (question mark in a circle) that opens an empty help viewer window.

I've had the same results on two systems. Has a Catalina update broken OctoMouse, perhaps?

Apparently, there's a packaging problem that's left the actual executable with incorrect permissions.

The solution is here.
