WebClient client = new WebClient();
client.DownloadFileAsync(new Uri(@"http://download.services.openoffice.org/files/stable/3.3.0/OOo_3.3.0_Win_x86_install-wJRE_en-US.exe"), "D:\\");
client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged);

button1.Enabled = false;
}
private void client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
double bytesIn = double.Parse(e.BytesReceived.ToString());
double totalBytes = double.Parse(e.TotalBytesToReceive.ToString());
double percentage = bytesIn / totalBytes * 100;
