# Downloading Installation Tools and Packages

Download the installation packages for the OMT Installer and the product of your choice from the Micro Focus Entitlement Portal to a secure network location. After download, validate the digital signature of each file. You can store all the packages on you local computer, as most of the tasks could be performed on it. To identify the files to download to your secure network location, see "Downloading and Installing the ArcSight Platform Installation Files" in the Release Notes for ArcSight Platform 23.3.

For installation, you must have the following files (each package requires its corresponding `md5` file for authentication):

    arcsight-platform-cloud-installer-XX.X.X.XXX.zip/.md5

    arcsight-suite-metadata-<version>.tar/.md5

    <product package file> tar/md5 [1 set for each product package you intend to install]

## Installation tools

The `arcsight-platform-cloud-installer-XX.X.X.XXX.zip` archive contains utility scripts and some templates used during the deployment process. The `aws_scripts/scripts` directory includes these scripts:

- `generate_aws_secrets`: Used to generate new Kubernetes Secrets for connecting from the cluster to the Elastic Container Registry (ECR). Generated credentials/secrets are valid only 12 hours after generation. For accessing the ECR after this timeframe, use this script according to Refresh the ECR credentials in the K8s.
- `init_efs`: Used to create the required folder structure on the Elastic File Storage (EFS) and assign correct ownership and permissions. You will use it when configuring EFS for the ArcSight Suite. Parameters for this script are discussed in the following sections. Execute this script without parameters to display the help.
- `upload_images_to_ECR`: Used for uploading the OMT and product images to the ECR to make them accessible to K8s. The script performs tasks in the background required specifically by the AWS ECR. Parameters for this script are detailed below. Execute this script without parameters to display the help.
- `workernodes-userdata`: Used indirectly for enabling worker nodes to join the Kubernetes cluster.
