In order to avoid the French Revolution, or some other violent social upheaval then your going to need to really make some serious changes to how the Kingdom of France is ruled and how the French state views its place in Europe. I would say you probably need to go back and make France have a much more British tilt to its policy. What I mean by that is that you need to change French history so that either the Hugenots win, and since that is rather hard, you need to have a reformed French state, where the urban middle class and the aristocracy are allied, where the population is trade oriented, and the state is eager to create a situation where trade is encouraged. I think that Toynbee had an idea about this, that France had two "axis:" one was in the east, and focused France on the continent, on wars in the trans-Rhine area and in northern Italy; the other was on the French Atlantic coast, and focused France on the ocean, and thus trade and overseas colonies. France was focused eastward, and thus you have the absolutist monarchy and the financial and social structures upon which that monarchy is based. A westward, ocean-focused France, with a pro-trade government (not necessarily monarch, you might have some kind of Parlimentry evolution, perhaps the Estates-General could become stronger, with the reformed Church the power of the Second Estate could be eliminated from power within the French state, and the Estates-General would be the First and Third Estate, something to check the monarch and strengthen the hand of the merchant classes) would battle the Dutch, English, and Spanish for global supremacy, but on the sea, not in pointless continental wars.
But that is just my opinion.
