Found other typos:
When deinstalling, on the "restart now/later" screen, the first sentence is "Le produit as été désintallé..." but it should be "Le produit a été..."
The second sentence shows: "[...] qu'il subsiste des fichiers dans leurs dossiers respectifs" but I think (I could be wrong on this one, but it should be verified) it should be without those "s".
In the same sentence, their is a "jusqu'au prochaine redémarage" but "prochain" should be without an "e".
