DataSight License Installation
In order to authenticate your license key, you must have Administrator Rights on the local computer.

Before attempting to authenticate your license, please make sure that:
· the License key is valid.
· the License key has not been previously installed on another system.
· the System is connected to the internet during authentication process.
· the System grants you administrator rights.

Follow one of the methods below based on your needs:

5.The license status will be updated if authentication is successful.

1. When you are not connected to the internet, you will be prompted to save your license file during your attempt to install DataSight's license key. It can then be sent for offline authentication.
2. Click Yes when the Authentication Error Window appears to save a copy of your license file ( *.Lic).
   
3. Navigate to https://authenticate.datasight.cloud/AuthenticationServer/AuthenticateFile.aspx to upload the unauthenticated file and download the authenticated file.
1. Alternatively, please email support@datasight.cloud with this license file, for the license file to be authenticated and emailed back to you.
   
4. When you receive your authenticated license file back, access the Install DataSight License Window either via the DataSight Evaluation Window upon launching DataSight, or from the File/License/Register Menu.
   5.Register the authenticated license using the Load License button.
   6.Select your license file from the browser.
   7.Then click Install.
   8.Your license key is now installed and you may start working on DataSight.
   
   Remember: Save your authenticated license
   Once a license has been installed it can be saved to an external file using the Save License button. This enables you to backup licenses to enable re-installation (for instance after an OS reinstall) without having to re-authenticate the license.
   
   
   Step 3 - Upgrade DataSight Service Manager
   1. Uninstall DataSight Service Manager.
   2. Download and install DataSight Service manager.
   3. Run DataSight Service Manager and Navigate to General Tab, verify the entries for service Username, Password and SMTP details are valid and then click Save (It is very important that you click the save button before running the service as the user used by the DataSight service for accessing Shared Network folders must be set under Windows Services before starting DataSight Service).
   4. Navigate to Service Status and click Start to start the service. (Please note service manager checks and executes any pending tasks upon starting).
