I think I just made it work with 7.2.1 by changing the adding 7.2.1 to the end of line 12 of config.php. The install kept failing till I made that change.

Thanks for the module Sandklock. It will come in very handy with the responsive templates because they make everything so long. It's great to be able to simply return back to the top on a mobile device.

I also backed up my database before the install, just in case something went wrong. Better safe than sorry.
