I found a video editor that is not free but you can illegally enter a registration code when you install the software. 
I was wondering if install the software and do all the set up on my USB   will I be able open the software on another computer and use it  (Without  entering the registration code and without installation)? So, I  guess  every time I want to use the video editor, I have to plug in my  USB and  use the editor.
Or can I burning the software on a CD so I can have a copy the software.   Can I just insert the CD and use the editor without installing   anything? (Same idea: (Without entering the registration code and   without installation)
I'm afraid that the registration code won't work someday (maybe the   company reject that code), so I won't be able to use the software   anymore. Just want to have a copy of the software and be able to use it   forever.
Thank you.
