"Can't make a temporary directory for the update download.."

Describe the bug
I'm on version 3.209 (1386). When prompted to install the latest update I follow the instructions but get this error - Screen shot here - https://www.dropbox.com/s/jjfdgo9f6gc47th/Screenshot%202020-02-19%20at%2006.51.41.png?dl=0

This sounds like some file permission issue on your system. I'm not sure what could cause this, maybe try to repair file permissions: https://support.apple.com/el-cy/HT203538
Did you recently restore your machine from a backup or something like this?

Of course you can also download manually via https://folivora.ai/downloads, but that's not a permanent solution.
