My apologies for not replying earlier to your kind tip about Photofiltre7, and am pleased to be able to tell you that I have now managed to instal it as the free edition.
Indeed, it took me a while to get it back, and I only succeeded with the one-to-one help of a friend.
Soon after I received your answer, my laptop crashed, and it is only yesterday that I obtained a new pc, this time a desk model, not a laptop. It has a larger screen than the laptop.

Am still wrestling with navigation on the new pc, e.g. I cannot figure why files saved in Word will open but it's impossible to edit them, as I used to on the laptop.

I renew my thanks for your unstinted help and patience.
