iMovie download fails with 'Unable to Download App' error

This morning, needed to download iMovie to my MBP, but it kicked up this message:


Unable to Download App

"iMovie" could not be installed.

Please try again later.


I tried again later, but got the same error.


Recently deleted FCP from this system. Haven't used iMovie in at least a decade. It won't even DL from the old listing in my App Store account. If need be, yes, will reinstall FCP. Thoughts, please.

How strange. Seems I had long ago uploaded iMovie to an external SSD. And App Store was looking for that drive, but without telling me so.


With the SSD connected, I was able to delete the old version and install the current version to the MBP. I don't actually need it now, but thought passing this along might help... someone. Sigh.
