  Two simple steps are necessary to download and install update files:    
       
  1. Click on the appropriate button to download available updates. A message box will open and ask you if you want to run or save the file on your hard disk.
Save the file in the appropriate sub-directory specified above. 		    
         
  2. When the download has finished, open the Windows Explorer, change to that directory and double-click on the downloaded file. The compressed file will expand itself. Choose the overwrite option to updated the old files in the sub-directory.
