You Have to extract it first, Then you will see a folder Named of Course...MMM-58-61_hackmii Installer.
Then in that folder you will see ....A apps folder and a wad folder.
Take the apps folder and copy that to the root of the Sd card.(This folder will have the MMM and Hackmii in it)
And do the same with the wad folder.(Put this on the root of the Sd Card too.)
No need for apologies. Picture's do help.
