You don't understand UAC in Windows 7 (Vista) No program has access to Program files or Windows folder, even you are administrator. You need to eleveate program rights - run it with right mouse as administrator.
You should install PSpad into multiuser environment, then config files will be stored in user profile. Version 4.5.6 is update only!!! Why people doesn't read several lines :-( You need to install lastest full version (4.5.4) and replace existing files with 4.5.6 -- <http://forum.pspad.com/read.php?2,57351,57352> PSPad freeware editor http://www.pspad.com
