Nalicity maps come in Zip format, with the files inside (.unr .utx etc) I don't think there's any other way to "install" them than to simply extract the files to the directory they need to be placed.
Mods come in .umod, and they're supposed to be linked to the setup.exe in the system folder, with the command line parameter "install" (no qoutes). but for some reasons this is messed up on some systems.
But hey, if it works as you're doing it know, why bother.
It never hurts to help ...
