# Crawling Module silent install
A silent install of the Crawling Module isn't interactive and must have parameters preset through the command line.
Only perform a silent install when you're faced with scenarios where an interactive install isn't an option, such as when building virtual machine images.

> **Tip**
>
> Use the [regular, interactive installation process](https://docs.coveo.com/en/3263/) when possible.
> A wizard will guide you through it.

Before you proceed:

* Ensure that your environment meets the [requirements](https://docs.coveo.com/en/3262/).

* Install [.NET 4.8](https://dotnet.microsoft.com/download/dotnet-framework/net48/) and [Visual C++ Redistributable (VCredist) 2015, 2017, or 2019](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170).

## Base Command

The following command installs the Crawling Module in the [US East region](https://docs.coveo.com/en/2976/) with default ports for Maestro and its workers:

```text
Maestro-setup.exe /VERYSILENT /SUPPRESSMSGBOXES /NORESTART /LOG=log.txt
```

The `/VERYSILENT`, `/SUPPRESSMSGBOXES`, and `/NORESTART` [Inno Setup](https://jrsoftware.org/isinfo.php/) flags are mandatory.

`/LOG=log.txt` creates a log file with details pertaining to the process, which could be relevant for troubleshooting.

Optionally, add the following flags to customize the Maestro settings. The settings can also be [modified](https://docs.coveo.com/en/3264/) after the installation.

## Maestro Port

Use flag `/CMaestro:Port=<PORT_NUMBER>` to specify the port from which you should access the Crawling Module component dashboard.

Default value is `5000`.

**Example**

`/CMaestro:Port=3354`

## Worker Service Port

Use flag `/CWorkerService:Port=<PORT_NUMBER>` to specify the local port that Maestro should use to send content update jobs to the Crawling Module workers.

Default value is `52816`.

## Database Port

Use flag `/CDatabase:DbPort=<PORT_NUMBER>` to specify the port that the database installed alongside Maestro should use.

Default value is `3306`.

## Name

Use flag `/CMaestro:Name=<NAME>` to specify a name for your Crawling Module deployment.

If the name contains whitespace characters, enclose the flag value in quotation marks.

**Example**

`/CMaestro:Name="My Crawling Module"`

## Environment

Use flag `/CMaestro:CoveoEnvironment=<ENVIRONMENT>` to specify whether the Coveo organization that you will link to your Crawling Module instance is a regular organization or a [HIPAA organization](https://docs.coveo.com/en/1853/).

Allowed values are `Production` and `Hipaa`.

## Region

Use flag `/CMaestro:Region=<REGION>` to specify the [deployment region](https://docs.coveo.com/en/2976/) of the organization that you will link to your Crawling Module instance.

Allowed values are `US_EAST_1` (Eastern United States), `EU_WEST_1` (Ireland), and `AP_SOUTHEAST_2` (Australia). Default is `US_EAST_1`.

Organizations in the [HIPAA environment](#environment) must be deployed in region `US_EAST_1`.

## Data Directory Location

Use flag `/CMaestro:DataDirectoryLocation=<LOCATION>` to specify the desired location of your [Maestro data folder](https://docs.coveo.com/en/3271#moving-the-maestro-data-folder).

If the path contains whitespace characters, enclose the flag value in quotation marks.

Default value is `C:\ProgramData\Coveo\Maestro`.

**Example**

`/CMaestro:DataDirectoryLocation="C:\ProgramData\My Favorite Apps\Coveo\Maestro"`

## Proxy URL

Use flag `/CProxy:Url=<PROXY_URL>` to specify your [proxy](https://docs.coveo.com/en/3264#proxy) URL. This URL must start with `http`.

## Proxy Username and Password

Use flags `/CProxy:Username=<PROXY_USERNAME>` and `/CProxy:Password=<PROXY_PASSWORD>` to specify your [proxy](https://docs.coveo.com/en/3264#proxy) username and password. The flags must be specified together; a username or password alone will be ignored.

Your password will be stored in Windows Credentials.

## API Key

If you are reinstalling the Crawling Module from a previous install, use flag `/CMaestro:Apikey=<API_KEY>` to enter your API key. This key should be saved in the Windows Credential Manager.

## Other

You can add custom settings to the [Maestro settings file](https://docs.coveo.com/en/3264/) with the following pattern: `/C<SECTION>:<KEY>=<VALUE>`.

**Example**

You provide a database connection string with the following flag:

`/CDatabase:ConnectionString="Server=localhost;Port=3306;Database=crawlers;"`
