Hello It looks like you installed or unpacked PSPad into program files as portable. Portable PSpad writes all files into it's folder but Program files folder doesn't allow it. To fix this problem, run PSPad with right mouse as administrator, open Program settings / System, check option "Multiuser environment" and confirm. Close PSPad and start it normally.
If you want to keep PSPad portable, move it to folder where PSPad has rights to write -- <https://forum.pspad.com/read.php?4,71840,71841> PSPad freeware editor https://www.pspad.com
