HTTP Error 500.21 - Internal Server Error
Handler "CCNetHttpHandler" has a bad module "ManagedPipelineHandler"
in its module list

I've tried preCondition="integratedMode"

This is exactly what I have in my web.config file
===================================================
<!-- Enable the handles in IIS 7.0 or later-->
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<add verb="*" path="*.aspx"
type="ThoughtWorks.CruiseControl.WebDashboard.MVC.ASPNET.HttpHandler,ThoughtWorks.CruiseControl.WebDashboard"
name="CCNetHttpHandler" preCondition="integratedMode" />
<add verb="*" path="*.xml"
type="ThoughtWorks.CruiseControl.WebDashboard.MVC.ASPNET.HttpHandler,ThoughtWorks.CruiseControl.WebDashboard"
name="CCNetXmlHandler" preCondition="integratedMode" />
</handlers>
</system.webServer>
</configuration>
===================================================

I am running windows 7 with iis 7

I am running web dashboard under it's own website. I'm not really sure
where to go from here.
