I have a console application with the Target CPU set to `Any CPU` and Target Framework set to `.NET Framework 4 Client Profile`.

It runs fine on my Windows 7 PC. However when I run it on my Windows Server 2003 System I get the following error. I have .NET 4.0 installed on here.

What am I doing wrong here?

Here's the contents of my `App.config` file;

```
<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <startup> 

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client"/></startup>
    <appSettings>
        <add key="chrome" value="20"/>
        <add key="OUTLOOK" value="230"/>
    </appSettings>
</configuration>

```
