You need to download the file in the members page by logging in with your username & password. After you run the .exe file, you should see the installation wizard as shown below. Just click on Next until it finishes the installation.
When done with the installation, open your mt4 platform and load the template by going to Charts > Template and look for ABCD as shown below.
There is also a video instruction on how to install and apply the template into your chart.
Hope this helps.
