Hi.
I don't know if the software can be altered. The Abbott libre software I use is the same as the one used for the Libre from the UK but the units are derived from the meter so are in mg/dl.
You cannot change the units on any of the meters from well known companies. ( some people in the past changed the units in error leading to confusion/wrong insulin doses etc. The companies were instructed to make the units fixed..)
I also hate telephoning in French, why don't you Email ?

The one time I e mailed Abbott France I received a reply the next day.
However, according to the website, the software for the Papillon Vision is the Auto-Assist, not the co-pilot (that's for the Navigator) The software is downloadable from the French site.
You can order the cable from Abbott France. The link for the software (logiciel) and bon de commande is
here;
'Commander un câble USB pour FreeStyle Papillon Vision, Freestyle Papillon Lite et FreeStyle Optium'
It will cost you 35 Euros(par for the course here). You will need to indicate which cable you need.
Unfortunately, to download the software you will have to create an account with Abbott France on their 'My Freestyle' site. ( I had to one to download the libre) There is a form to fill in with name, address, age etc. There is provision for you to opt out of being sent anything else though.
(I suspect part of it is because they have to get evidence of your express consent to the conditions .It's complicated but lets say it's an improvement on a few years ago when you couldn't download any of the companies programs because of French medical data protection laws)
