wont work on Windows Xp (faild to get ConnectEx) about badvpn HOT 5 CLOSED

That's a strange error. Apparently the OS doesn't support the ConnectEx 
function which is required. But then, MSDN states WinXP does support it, 
http://msdn.microsoft.com/en-us/library/windows/desktop/ms737606(v=vs.85).aspx .

Perhaps there is something wrong with your OS, or the MSDN is wrong about 
ConnectEx being supported on XP? Do you happen to have a very old version of XP?

Hi! I've tried it with a virtualized XP (SP3), and it works flawlessly.
Unfortunately i can't check the version of the problematic xp until tomorrow.

Do you have any suggestion? What lib should i install/reinstall?

Thank you!

I've got the version info:
Both of them are XP SP3 (Professional), and "cmd" tells Microsoft Windows XP 
[Version 5.1.2600]

It appears then your system is broken in some way, I don't believe there's 
anything I can do.

"Microsoft Fix it 50203" resolved this issue.
