My question is: am I really required to run WinSCP with admin privileges every time I simply want to change some configuration options? That doesn't seem right, no other software does that. Am I missing something and is there another way to solve this?
C:\Username\username\AppData\Roaming\WiSCP.ini. WinSCP will do it for you if you switch to Windows Registry (running as admin) and than back to INI file (running as non-admin).
