... when I use File::Copy or Win32::CopyFile, I get the output file as requested along with the error.

The error variable $! is only valid immediately after an actual system error, which must be recognized by other means. If $! is nonzero that doesn't indicate an error in the preceding code. The value can come from anywhere. So you are using it wrong in your code below. 

if($keepfile)
{
    my $dest;
    sleep 1;
    eval{
        $dest = $$appconfig{"destination"}."\\$filename";
        Win32::CopyFile($file,$dest,1);
    };
    if($!)
    {
        report("Error: Unable to move file to destination - ".$dest."\
+n $!");
        #die;
    }
}

Moreover, why do you run the critical statements under eval()? It will only mask some errors. If the eval() is there for a reason, you ought to inspect $@, not $! after eval finishes to detect possible errors. ($@ is unlike $! in that respect, if it's set after an eval(), there was an error.)

I believe your program is running just fine, the message in $! is irrelevant. Wy you can't copy the file using print() I don't know.

PS: The behavior of $! is as described in Unix systems. I don't know for sure about Windows.
