Internal Server Error when running co2mpas

[pfung-maker]

Hi! I was trying to do the quick start by the following code:

Run co2mpas and open the output folder. $ co2mpas run ./input/co2mpas_conventional.xlsx -O ./output -PL $ start ./output

A page of 'Internal Server Error'. Error message as below:

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Any ideas of why caused this? Thank you in advance.
