koop sample app not starting

[mhogeweg]

following the instructions to install the koop sample app on windows, I'm getting the following error when accessing http://hogeweg.esri.com/koop. This while the node samples using express work just fine: http://hogeweg.esri.com/node/express.

iisnode encountered an error when processing the request.

HRESULT: 0x2
HTTP status: 500
HTTP subStatus: 1002
HTTP reason: Internal Server Error
You are receiving this HTTP 200 response because system.webServer/iisnode/@devErrorsEnabled configuration setting is 'true'.

In addition to the log of stdout and stderr of the node.exe process, consider using debugging and ETW traces to further diagnose the problem.

The last 64k of the output generated by the node.exe process to stderr is shown below:

Application has thrown an uncaught exception and is terminated:

do you see an express folder inside the node_modules folder next to server.js after running npm install (after cloning the repo?)
