i have looked everywhere for the bin folder someone please help me.
there is no bin folder with mc 1.6.2; to install modloader follow directions of the modloader thread, to install forge use the forge installer. After installing one or the other you just drop mods in the mods folder. Basically bin was replaced by versions/<version>/
Then how can I install WorldEdit? I haven't played minecraft in ages and wanted to today, only to find the latest version had a total revamp of the library files. I tried installing SPC 1.5.2 to the 1.5.2.jar in Versions/1.5.2
