# Adding an additional Data Source to your dox42 Add-in

To ensure that the dox42 Add-In can access your specific data, you must first add the respective data sources to it.

> [!NOTE]
> Basic and additional data sources
> 
> dox42 offers **basic data sources** which are automatically provided with your dox42 Add-In installation. In addition to that, there are **additional data sources** which enable access to specific data sources or systems. The additional data source is developed and licensed as an additional module by dox42 and, once purchased, must first be added to the dox42 Add-In before it can be used.

## Prerequisites

- Make sure that Windows Identity Foundation is installed and activated on your Windows computer. Otherwise, you will get the error `Microsoft.IdentityModel could not be found`. To activate Windows Identity Foundation, go to the **Control Panel > Programs > Turn Windows Features on or off** and select the checkbox at **Windows Identity Foundation**.
- .NET Framework 4.5.2 or higher is installed on your Windows computer.

## Steps

1. Download a data source from [https://www.dox42.com/de/Modules/Download](https://www.dox42.com/de/Modules/Download).
