# Export custom installer configuration

{% tabs %}
{% tab title="Windows" %}
When creating an installation package with the ***Custom installer manager***, an installer file is necessary to determine what to include in the installation configuration. Creating an installer file for each new version is risky since you have to repeat the process manually every time. Instead, it is possible to create the configuration once, save the resulting `.rdi` file, and reuse it as many times as needed.

#### Creating an installer file <a href="#creating-an-installer-file" id="creating-an-installer-file"></a>

1. Head to ***Tools*** – ***All tools*** – ***Custom installer***, click on ***Export custom installer configuration***.
2. Check/uncheck options according what is needed and select the workspaces to be included. See [RDI file generation options](https://docs.devolutions.net/rdm/installation/client/custom-installer-service/option-selection/) for more information about the different options to choose from.
3. Click ***Export***, then save the `.rdi` file locally.

This file can be used in the ***Custom installer manager*** when creating an installation package.

{% tab title="macOS" %}
Remote Desktop Manager for macOS does not support the custom installer. Only a `.cfg` file can be used; `.rdi` and `.msi` files are not available on macOS.

This article describes how to export a `Default.cfg` file from Remote Desktop Manager macOS and apply it to new installations. When the application opens for the first time, users can choose to load the `Default.cfg` file, which automatically applies the predefined settings and workspaces

#### Export and apply a default configuration file <a href="#export-and-apply-a-default-configuration-file" id="export-and-apply-a-default-configuration-file"></a>

1. In Remote Desktop Manager, click on ***File*** – ***Export*** – ***Export settings***.
2. Select the required settings, then choose which workspaces to include.
3. Click ***Export***.
4. Save the `Default.cfg` file.
5. For new installations, create the `com.devolutions.remotedesktopmanager` folder in `/Users/<your user>/Library/Application Support/` with the `Default.cfg` file.
6. When Remote Desktop Manager opens for the first time, it prompts the user to use the `Default.cfg` file. If the user clicks ***Yes***, the settings and workspaces are loaded.
