The MIME::Lite documentation for ->send specifically says:

... Or, for non-Unix users:

    MIME::Lite->send("smtp");
[download]

Your code looks nothing like the documentation. It seems to me you are not on a unixish system, so maybe it would be a solution to use what the documentation says?

I do have a win32 system (I think I mentioned it before).
but actually the documentation also says

On Win32 systems the default setting is equivalent to:
    MIME::Lite->send("smtp");
[download]

so... ?
Anyway just so I won't skip any possibility,
I tried to sub the
MIME::Lite->send('sendmail', 'C:\\xampp\xampplite\sendmail\sendmail.exe'); line for
MIME::Lite->send('smtp','C:\\xampp\xampplite\sendmail\sendmail.exe');
making it die saying:
SMTP Failed to connect to mail server: Invalid argument
The same goes when I try MIME::Lite->send('smtp','sendmail','C:\\xampp\xampplite\sendmail\sendmail.exe');
So just to be safe I even tried
MIME::Lite->send('smtp');
which dies saying class method send must have HOW... arguments

I have no idea whats the problem.
Also I find my code exactly like in the documentation as it is a copy/paste of it with the from/to strings changed.
If you find my code that off-base, please tell me how to fix it.

I have no idea whats the problem.

Why? Try some flavor of

    ### use Net:SMTP to do the sending
    $msg->send('smtp','some.host', Debug=>1 );
