Hi there,

it seems there has been no OS version checking before the call of this function since it is only available as of Windows Vista. I got the same error on my XP box.
See:

Yes, this version is working, I will use it and look if all is good.

What was it?

Thanks for your post. This bug was added to the tracker:
https://winscp.net/tracker/729

Also, I have sent you an email with development build for testing. Thanks.

With 5.0.1 Beta I have the following error when starting, so just after installing before the first start:

Der Prozedureinsprungpunkt "GetTimeZoneInformationForYear" wurde in der DLL "KERNEL32.DLL" nicht gefunden.

This is german and could mean:

The procedure entry point "GetTimeZoneInformationForYear" could not be located in the dynamic link library "Kernel32.DLL

I installed previously 5.0 beta over stable 4.3.4 and this beta worked (without icon only).

My System is Windows XP SP3 Prof.

Kind regards,
