Minecraft, installing ICBM mod with current 1.7.4 version?

I have been trying to get this mod to install and it either crashes, does nothing, or some odd response like simply restarting the launcher.

It has been unclear if I have to have a profile selected for the latest version, or a specific version. (As in, does the mod only work if I add everything to a 1.6.2 copy, or do I need to use 1.7.4?)

The frustration has been overwhelming. I follow directions but it leads me nowhere. In each video I have viewed, each problem I have seen resolved on a forum takes me in a promising direction, but they are in another version, not as new as 1.7.4. I'm trying to figure out what I'm doing wrong.

I have tried adding everything into 1.6.4 mods, as it was called. I did again with 1.7.4 mods, both with identical results: nothing happened. I took every file, folder, and piece related to mods and dumped them all in, to no noticeable change.

I need modern directions to installing this mod. This is what I have done so far:

-Made a proper copy of version (i.e. 1.7.4 mods). Including renaming files and adding "mods" after "1.7.4" in the.jsn file.
-Download and extract mod files to above.jar
-Delete META-INF (this seems to be a popular thing to do)
-Made new profile that uses the above mod version
-Launch Minecraft
-Play with newly installed mods, or at least this is what is supposed to happen.

I need a map to follow. One that works with the newer versions that are out. People who have had trouble installing were in older versions and those are the only answers I find.
1) Do I need to install mods to the newest version, or one that they mention (as in, 1.6.4)?
2) Is there a step I'm missing?
3) This really should seem simple, yet I'm getting no successful results.

The answer is that this will ONLY work on 1.6.4. There's no exception. If it really doesn't want to work download Technic launcher http://www.technicpack.net/

Hope this helped!
