WinSCP-5.16.6.RC-Setup.exe is not a valid Win32 application.

Hi Martin,
I've downloaded WinSCP-5.16.6.RC-Setup.exe from you and cdn, both files are the same but both give the error message WinSCP-5.16.6.RC-Setup.exe is not a valid Win32 application.
I'm using win xp sp3 and I'm currently running Version 5.15.2(Build 9590)
Does the new version still support XP?
Thanks.

Installer of WinSCP 5.16 does not support Windows XP/2003 anymore.
WinSCP application itself still does work on Windows XP.
You can use Portable executables download to get the application without using the installer.

I have updated the documentation to cover this:

Many thanks Martin, I will try the portable download.
