You have to install on your web site under the public_html/httpdocs/www/html folders.
Basically script can be installed where you can upload your index file on your website. You can create a folder under that public directory and upload files there.
Example:
http:yoursite.com/autoresponder/
You upload script files in 'autoresponder' folder.
Our scripts are NOT desktop software. (Means they can't be installed on your PC.)
Advantages of installing on your website are:
* you can access your script admin panel from anywhere in the world. (with internet access)
* you can send emails using your website mail server. Not your ISP. (unless your website is hosted by your ISP)
* you can use advanced features like email subscriptions, sending automatic preset follow ups, real time updates etc.
