The only fix I have been able to make is uninstall 5.1.4 completely, reboot, and install WinSCP 4.4.0.
Is there a bug here?
C:\Program Files(x86)\WinSCP\Putty. When using redirection-inaware application (such as PuTTYgen), Windows redirects writes to system directories to user profile folder. Files created this way are only visible from other redirection-inaware applications. This is not a case of WinSCP nor Windows Explorer. Make sure you generate your keys to a folder you have a write access to. Or run PuTTYgen as admin.
