Executable file won't open/run

I just downloaded the most recent version (2.1.3), double clicked it - and nothing happened.

I’m trying to install it on an old Windows 7 machine.

Any idea why this would be happening, and suggestions for a solution?

Did you used to have an older version of Audacity on this machine? The 2.1.3 installer should have asked you if you want to reset all settings and preferences. Did you say yes?
