As for the French language, this happened to me a few months back when my DH
download a trial of the new version of MS Office. For some reason the
English dictionary got deleted (apparently this was a problem with the new
version I was advised by some very kind soul here). Shortly after that I
had major computer issues and so DH redid my whole system eliminating the
issue. You don't have to do that!!! All you have to do, I was told, is
pull out your old version of office and have it install the dictionary only,
then select English as the language for spell checker.
