<p>I'm creating an installer for a website that uses a custom event log source. I would like our WiX based installer to create that event log source during installation.</p>

<p>Does anyone know the best way to do this using the WiX framework.</p>

Wix has out-of-the-box support for creating event log sources.
Assuming you use Wix 3, you first need to add a reference to WixUtilExtension to either your Votive project or the command line. You can then add an EventSource element under a component :
```
```
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
    xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">

    <Component ...>
        ...
        <util:EventSource Log="Application" Name="*source name*"
           EventMessageFile="*path to message file*"/>
        ...
    </Component>
```
```
If this is a .NET project, you can use EventLogMessages.dll in the framework directory as the message file.
