Install MID-less Agent Client Collector on a Windows machine to enable sending data from the agent to the instance through the cloud. Sending information through the cloud allows the MID Server to be used for more persistent resources.

## Before you begin

* Install the ITOM Cloud Services Core (sn_itom_cloud_svc) plugin.
* Onboard your instance to use ITOM Cloud Services. For details, contact Customer Support.
* Configure an agent registration key. For details, see [Configure an agent registration key](https://www.servicenow.com/docs/mJI5LSijqIKeb~P5Xz42dA "Configure an agent registration key so that you can deploy MID-less Agent Client Collector. Deploying MID-less Agent Client Collector enables you to use the MID Server for more persistent resources.").
* Role required: agent_client_collector_admin

## About this task

For details on sending data through the cloud in a MID-less deployment, see [DEX Architecture](https://www.servicenow.com/docs/access?context=dex-architecture&version=zurich&pubname=zurich-it-service-management&ft:locale=en-US).

## Procedure

1. Retrieve the publicly accessible gateway URL, based on your location.  
   * AMER (Americas): itomcnc-prod-gateway-amer.sncapps.service-now.com:443
   * EMEA (Europe): itomcnc-prod-gateway-emea.sncapps.service-now.com:443
   * APAC (Asia Pacific): itomcnc-prod-gateway-apac.sncapps.service-now.com:443
   {#acc-install-ics-windows__ul_tsf_fpf_wfc}
2. On the Windows server where the agent is installed, enter the following command:  

       msiexec /i <msi_file_path> /quiet /qn /norestart CONNECT_WITHOUT_MID="true" ACC_CNC="<gateway_endpoint>" REGISTRATION_KEY="<registration_key>" INSTANCE_URL="https://<instance_url>"

   The following table shows the parameter values in the command.
   {#acc-install-ics-windows__table_usf_fpf_wfc__entry__2}

   | Parameter | Description |
   |-|-|
   | CONNECT_WITHOUT_MID | Specify true to enable MID-less Agent Client Collector installation. If you don't specify a value, the regular MID Server websocket installation is invoked. |
   | ACC_CNC | Specify a public gateway endpoint for Agent Client Collector. |
   | REGISTRATION_KEY | Active and valid registration key for the agent to communicate with. |
   | INSTANCE_URL | ServiceNow instance that the agent is registered with. |
   | ACC_ALLOW_LIST | Optional string. To disable the allow list, set ACC_ALLOW_LIST=0. By default, the allow list is enabled. Note: Disabling the allow list compromises your system's security and is intended as a temporary measure while you're updating the allow list. After completing the update, enable the allow list by setting ACC_ALLOW_LIST=1. |
   | ACC_VALIDATE_SIG | Optional string. To disable verification of the installer certification validation, set ACC_VALIDATE_SIG=0 that you can add to disable the verification of the installer certification validation. By default, validation is enabled. Note: Disable the certification validation only when using non-standard signature validation tools. |
