error installing coldbox

Hello,
I just tried to install coldbox via following code in commandbox:
coldbox create app
I get following folders

Atfer creating a new site in IIS I get following error when I try to browse the site.

Could not find the ColdFusion component or interface coldbox.system.Bootstrap.

Is there something missing?

We use Coldfusion 10 on windows server 2008 and IIS7.

Can anyone help?

thanks Inge
