  1. Did you use the installer from the following link: ?
  2. Did you accept the certificate when the pop-up appeared?
  3. Do you have Hyper-V Role enabled?

On what Windows OS ware you installing it? Additionally, we released a new beta a few days ago, can you please confirm that this happens for you using the latest MSI available?

2. yes the certificate is the one in the installation progress. Could you please post the output of: PnPutil.exe -e.

alexpilotti : Currently I'm using your windows server that you published in your web site. Ok I'll try to use the latest MSI but Could you please give me a link from which I can download. aserdean : Tomorrow Incha'Allah I will post the output of PnPutil.exe -e because I'm not in the office. Thank you all.

We updated our installer today. It should work out of the box now. Link for the installer is: (the one you can find on our website). Installer is automatically updated as we integrate new patches.
