Google Chrome does not support Java so you will need to install this from a different browser application, such as Microsoft Edge.
Next, Login to improveit 360 as the System Administrator User for your organization. Only System Administrators have access to the Data Loader.
Navigate to the Setup menu. Click on your Username in the upper-right corner of your improveit 360 page. Clicking on your Username will expose a dropdown menu. Here you will find the Setup menu:
From the Setup menu, use the Quick Find search bar and search the words "Data Loader". Under the "Data Management" section, click on the Data Loader menu:
Choose the appropriate installer file for Windows or Mac (whichever is applicable to your computer)
