Download? What and why? You have to install the updates and it will happen automatically unless you have blocked the updates with some chemical. If Your system is not changed, but still it won't update automatically, try to get know, why it happens. But before doing everything else try to start updating manually and if this works, probably you'll get this feature also. But remember, it works really only with Excel and may not work correctly with all languages.
i'm trying to install it on widows 7.I mange to install office 365.but cannot update.it says already updated to latest version ad cannot update.
