License problem with CenOS

Hello!
I have a some license problem when i try to use krpano on CentOS.
There is no GUI, so, i cannot use krpano tools (its need GUI!) to accept license key.
I tried another way - install krpano on another linux (Ubuntu) with GUI, when copy installed krpano to CentOS,
but when i tried to make pano - it show me "demo version"...
How can i move installed krpano to another linux, or how to register krpano without GUI?

Well, i've found answer on forum...

run command

./krpanotools register ####################### (license code)

now its work fine
