### Introduction

Installer IDs are unique identifiers assigned to each group and the Sanas Account. When updated on a user's machine, the Installer ID helps Sanas pre-configure the app based on the user’s group configuration and enables auto-provisioning when using app authentication modes such as Auto-activation and Single-Sign On. Installer IDs are relevant only for Sanas App users.

Learn more about the available [authentication modes](https://help.sanas.ai/portalv3/docs/app-authentication-modes) for the Sanas App users.

#### How it works

The Installer ID serves two purposes during App activation:

- **Group identification** — Sanas uses the Installer ID to identify the group the user belongs to, then pre-configures the App based on that group's settings (language, accent, authentication mode, etc.).

- **Auto-provisioning** — When a user activates the App for the first time, Sanas checks whether the user exists in the group associated with the Installer ID. If the user exists, they are granted access. If not, Sanas automatically creates the user in that group and grants access.

Ensure the Auto Provisioning toggle is enabled on the intended groups. Navigate to **Settings** > **Configuration** > **Application Authentication** > Ensure **SSO or Auto-activation** is configured > Ensure the **Automatic User Creation** toggle is enabled **.**

#### **Locate the Installer ID**

Each group has a unique Installer ID. To find it:

1. Log in to the [Sanas Portal (opens in new tab)](https://portal.sanas.ai/) with your credentials.
2. Navigate to the **Get Sanas** page.
3. Select the group for which you need the Installer ID.
4. Copy the Installer ID and save it securely.

### Before you begin

- Ensure you have access to the user's machine to update the Installer ID, either directly or through your endpoint management software.
- Ensure you have copied the correct Installer ID for the target group from the **Get Sanas** page on the Portal.

### Update the Installer ID

The Installer ID can be updated at two stages:

- [**During installation**](https://help.sanas.ai/portalv3/docs/update-installer-id-on-the-sanas-app-user-s-computer#during-sanas-app-installation) — Set the Installer ID as part of the initial app installation.
- [**Post installation**](https://help.sanas.ai/portalv3/docs/update-installer-id-on-the-sanas-app-user-s-computer#post-sanas-app-installation) — Update the Installer ID on machines where the app is already installed.

Choose the applicable stage, platform, and method below.

#### During the Sanas App installation

> _Note: The below command can also run through endpoint management software to update installer IDs on centrally managed user machines._

##### Windows

**Method 1**: **App installer**  
Enter the installer ID in its respective field when prompted during installation.

**Method 2**: **Command**  
> _Note: Replace the placeholders <file\_path> and <installer\_ID> with the actual values._  
> _For example, here is a sample command for msi file type:_  
```plaintext
msiexec /i "C:\Users\Acme_inc\Downloads\Sanas-5.2.11-x64.msi" installerid="XXXX-XXXX-XXXX" /q
```

- **.msi** installer

```plaintext
msiexec /i "<file_path>" installerid="<installer_ID>" /q
```

- **.exe** installer

```plaintext
"<file_path>" /installerid="<installer_ID>" /q
```

```plaintext
& "<file_path>" /installerid="<installer_ID>" /q
```

#### Post Sanas App installation

> _Note: The below command can also run through endpoint management software to update installer IDs on centrally managed user machines._

##### Windows

> _Note: Replace the placeholders <installer\_ID> with the actual value._

```plaintext
reg add "HKLM\SOFTWARE\Sanas.ai\Sanas" /v InstallerId /t REG_SZ /d "<installer_ID>"
```

##### macOS

> _Note: Replace the placeholders <file\_path> and <installer\_ID> with the actual values._

```plaintext
sudo defaults write /Library/Preferences/ai.sanas.SanasApp.plist InstallerId "<installer_ID>"
```
