7.3.3 failed module install

i have followed the instruction from the developer for installing the module but it fails to install

please help

This is a directory problem. You probably have misplaced the module.

It should be in /modules/andrew/module_name/

Directly after you must have the files classes, templates, install

You probably have an error like this /modules/andrew/module_name/module_name

Or /modules/andrew/andrew/module_name/
