Download an mse file


I want to update my script on startup. How can i download the file from my server without popups.
I tried "Microsoft Web Broser" ActiveX, and it works, but popups a window.
I tried "Microsoft.XMLHTTP" and save the responsetext to a file, but this works only with ASCII characters, and did't work with an encrypted maxscript file.

How can I download my file?
Please help me!
