I'm having a problem with updates - this just began happening recently. The apps download normally, but when the installer goes to work I get an error: "Repertoire de destination non defini." My imperfect French translates this as "Destination folder is not defined."

This happens with all updates, and even when installing new applications. But as I said, it's a recent development.

That did it, thanks. I searched for threads before posting, but apparently I didn't use the right terms.
