You should not use Liteicon, nor XtraFinder or Totalfinder and what have you.
Yo CAN change icons in OSX very easy in the OSX way:
select the folder or the file of which you want to cange the icon, hold Alt(option) when you select it and choose "getinfo", we call this getinfo panel 1.
Then selcect a folder or file which's icon you want to use, hold Alt(option) when you select it and choose "getinfo", we call this getinfo panel 2.
Now in getinfo panel2, select the icon (top left), in the Finder menu choose "copy", then select the icon to be changed in getinfo panel 1, and in the finder menu select "paste".
