Transfers initiated in the IBM Aspera Shares web application are conducted using the IBM Aspera Connect Browser Plug-in. The Connect Plug-In is an install-on-demand web browser plug-in that facilitates high-speed uploads and downloads with an Aspera transfer server.
The Connect Install Dialog
When a user first logs in, Shares checks if the Connect Plug-In has
been installed on their browser. If they have an outdated version or do not have the plug-in
installed, Shares prompts the users to download and install the
plug-in. 
Clicking
Download latest version connects the user to Aspera's CloudFront CDN
from which they can download the Connect Plug-In installer.
Each page of Shares checks for the presence of Connect. If Connect is missing, Shares prompts you to download the plug-in. To suppress Shares from prompting you to install Connect on each page, go to your Preferences page and set the value of Suppress Connect Install Dialog to true.
