This method downloads the update represented by CurrentUpdate. To find an update to download, use CheckForUpdate, CheckForUpdateAsync, or ShowCheckForUpdateDialog.

To receive notifications as the download progresses, add an event handler to the DownloadUpdateProgressChanged event.

This method does not block the calling thread while the download is being performed. To block while downloading the update, use DownloadUpdate or ShowDownloadUpdateDialog.

You can use the CancelAsync method to cancel asynchronous operations that have not been completed.
