It has the latest versions of minecraft, what i want is one of the older versions, for some reason it wont go any farther than the 1.8 versions.

I'm trying to get a different version of Minecraft launched for tekkit. However i downloaded the one i wanted (1.7.10) and it don't accept the file. Guessing the file might be broke or something. Any advice or tips? Tried searching but due to the vague resemblence between "version" be it MC or tekkit, the searches are so vast, I couldn't spent any more time searching.
