Re: unexpected variant error
Do you get the message even before the login dialog appears? What happens if you close the message? Did you install any translation?
Problem solved : I had WinSCP 3.6.8 installed on this computer. I installed the 3.7.6 version without de-installing the old version, and I got the problem. Now I have de-installed and re-installed WinSCP, and it is working. I am not really sure of what happened.
Anyway, thanks for your quick answer.
