So, we’re talking a few model of Minecraft newer than 1.5, which means that the sport organizes its recordsdata barely differently.
Seeing as you may have a number of “profiles” in the newer launcher, and that they will have completely different versions, one may ask: How may they manage all these totally different variations? It is actually quite easy if you give it some thought. Basically, the game uses a folder containing multiple other folders, each of these containing a .jar and dats file for a sure version of Minecraft.
First off, navigate to the AppData folder where the Minecraft recordsdata are positioned. Assuming you’re running Windows 7, open the file browser and search for “%appdata%”. The first outcome ought to be the correct folder. Alternately, navigate to it manually by going to: “C:/Users/[your username]/AppData/Roaming”. Notice that minecraft servers is a hidden folder, so enable “Show hidden folders” if you don’t have already got it enabled.
Your .minecraft folder needs to be positioned here; open it. There ought to be a folder labeled “versions”, which is what we’re going after. Open it and look for a folder with the same title as the Minecraft version you are on the lookout for; in your case, it will be named “1.7.4”. Inside this folder ought to be the jar file you’re looking for.
