    Hi @Salim Njopeka ,

    The error is due to DeploymentDownloadException.

    According to the Troubleshooting Errors Documentation: ClickOnce cannot Establish a network connection to the server. Examine the server's availability and the state of your network.

    Your target update address is not available.

    Best Regards,
