Liberkey is meant to be portable. So you can move the whole folder anywhere you want. But take a few precautions like:
1.Make sure Liberkey menu is not running. The tray icon should not be visible.
2.Make sure that all programmes from Liberkey are closed.
3.Double check TaskManager to see none of the processes are running - LiberkeyMenu.exe, LiberkeyPortablizer.exe
So you are good to go
