Script Download File from internet using Windinet.dll and Overwrite old version

I need a simple script that can download a zip file from internet (link given in chat later).

The script should do (in sequence)

1. Download the zip file from given link
2. Save the file at Terminal Folder location (the one that usually when we open data folder for our MT4/5)
• If there is exisitng zip file, it will overwrite
3. Unzip the zip file (inside got 3 folder, MQL4, template and tester)
4. Copy these folder and paste it (overwrite) at the initial terminal folder. (Update the ex4 files)
5. After complete the overwrite, Zip file is deleted.
6. Message box will pop up and inform me the process is completed.
