I copied the programfiles/pspad directory my USB thumb drive and took it to another PC that did not have PSPad installed and it worked fine including having the FTP servers defined and able to connect.
This is important not only for USB drives, but for disaster recovery purposes having software that can be simply backup and runs when restored. -- <http://forum.pspad.com/read.php?2,35039,35043> PSPad freeware editor http://www.pspad.com
