Re: Sims 4 installation vanished - why, and how do I reinstall?

Incidentally - I am certain I did not accidentally delete the installation (I've been a computer programmer since 1974, please don't deign to tell me I don't know what I'm doing), and nobody has access to my home - and computer - but me. So please don't try to tell me that I deleted it by accident.

Also please don't try to tell me to run it without CC and see what happens. I can't run it without CC. IT'S NOT INSTALLED. THAT'S THE PROBLEM.
