First of all the jar isn't an operating system, the operating system is Windows 32bit/64bit, Mac(don't know what macs system is), and Linux. It doesn't ask if you think your version of java is the problem or not, it asks you what version of java you have so you put the version of java you have. Why can't you say what antivirus you have? There's no way you don't have a .techniclauncher folder if you're using the Technic launcher, For Windows7 look in C:\Users\(UserName)\AppData\Roaming\ or open the start menu and in the search bar type %appdata% and open roaming. How did you install it, did you place the contents in Minecraft.jar/modpack.jar or did you place the zip in the texture packs folder. Lastly it's time for some uncalled for insults, god dammit how the hell do you fuck up installing a texture pack, i mean Jesus fucking Christ, are you that fucking incompetent? This has been "Minute With Dumb-ass", you are now free to get bent.
