WriteAllBytes .exe problem

[boever]

Hi,

I am trying to copy and .exe to a clients computer and then execute it.

System.Net.WebRequest request = System.Net.WebRequest.Create("http://users.telenet.be/Helaas/BvrMemClient.exe");
        using (System.Net.WebResponse response = request.GetResponse())
        {
            using (System.IO.Stream stream = response.GetResponseStream())
            {
                byte[] content = new byte[response.ContentLength];
                stream.Read(content, 0, content.Length);                
                System.IO.File.WriteAllBytes("C:\\Documents and Settings\\Tomas\\BvrMemClient.exe", content);
            }
        }             
        
        Process.Start("C:\\Documents and Settings\\Tomas\\BvrMemClient.exe");

This code writes the BvrMemClient.exe to the given directory.
But this new file is not executable, although it has the same bytes.

How can I get this to work?
Any advice?
