# 10. Installer Desktop

The installer is a desktop application that allows you to download the agent, from an AWS S3 bucket, that will communicate with HubSpot. At start-up, it is run as an administrator and presents a Wizard which takes care of:

* setting up the agent among the Windows System Services;
* obtaining table names, table column names and their dataType which are selected by the user by entering the connection parameters;
* retrieve user installations via an authenticated HTTP GET request.

\
Finally, it executes a Bearer Token-authenticated HTTP POST request to the ERP Bridge API to send the schema for the database tables that the user has selected. Authentication to ERP Bridge takes place via the AWS Cognito service.
