Thank you all, Keef, Mike-Bracknell, le Pingouin and LH2! Thanks to your joint help. I have downloaded and installed the 3.3 version and have GB English and Spanish. It took less than five minutes and appears to have gone without a hitch. Now I will be setting out to rediscover my talents learned on Visicalc on my first Apple in 1976! Visicalc was the only application that I had then. My business depended upon it and upon half a dozen databases that my wife and I wrote from scratch in Basic.... I still have at least two Apples here!
I am extremely grateful to you all and can only say that you have shown yet another of the marvels of PPRuNe. An excellent antidote to the nay-saying and backbiting that is all too common in some of the other sections of this great site.
