What about War of Austrian Succession 1740-1748. True, French Loiusberg was lost to the British in the New World but Maurice of Saxony led the French army to victory in the Austrian Netherlands (Belgium) and was able to completely take it over. Its ally Spain, was less successful in Italy and Franc exchanged it winnings in the Austrian Netherlands for expansion of Spanish interests in Northern Italy when peace came in 1748. While it was not a clear cut victory for France they did end the war with the upper hand.
I disagree, that war featured 2 conflicts, the Spanish-French alliance battling the British for control of the New World, and the continental conflict on Austrian Succession. France lost both of these conflicts.
I do not see it that way. For sure French support for Bavaria's claims to Bohemia and Upper Austria in addition to the title of the Holy Roman Emperor was unrealistic. But in Italy, France-Spain-Genoa fought Austria-Savoy to a draw. An Austrian attempt to take over Kingdom of the Two Sicilies failed. I agree that battle in the New World went against France and an attempt for Stuart restoration in Great Britian failed in the "Fourty-Five." But for sure the greatest military success of the war was the decisive French victory in the Austrian Netherlands. When peace came, France was able to trade away the Austrian Netherlands for return of all New World positions lost to Great Britian AND expansion of Spanish position in Northern Italy. All in all, a net gain by France-Spaln over Great Britian-Austria. And this is not to mention the Austrian loss of Silesia to French-backed Prussia. For sure France did not "win" the war but at the peace in 1748 the Franco-Spain alliance was the net winner in terms of territory.
