So, we're speaking a couple of model of Minecraft newer than 1.5, which means that the sport organizes its information barely differently.
Seeing as you'll be able to have a number of "profiles" within the newer launcher, and that they will have different variations, one may ask: How might they handle all these totally different versions? It's truly fairly simple if you happen to give it some thought. Mainly, the game makes use of a folder containing a number of different folders, each of these containing a .jar and dats file for a certain version of Minecraft.
First off, navigate to the AppData folder the place the Minecraft files are positioned. Assuming you are running Home windows 7, open the file browser and seek for "%appdata%". The primary consequence should be the right folder. Alternately, navigate to it manually by going to: "C:/Customers/[your username]/AppData/Roaming". Word that AppData is a hidden folder, so enable "Show hidden folders" if you do not have already got it enabled.
Your .minecraft folder ought to be positioned here; open it. There should be a folder labeled "versions", which is what we're going after. Open https://djw360.com/ and search for a folder with the identical title as the Minecraft version you're on the lookout for; in your case, it will likely be named "1.7.4". Inside this folder ought to be the jar file you're in search of.
