I have a fresh installation with Server 2012 R2. It's configured with AD, DNS etc.
I have added the Remote Access role because I want to connect to it over PPTP VPN (didn't activate direct connect as I dont want that).

It's no problem to add the role, but when I'm doing the last step it's hanging as the picture show.

I have reinstalled the role several times and made restarts after each reinstall.

I have to force it to close. After that I actually can see the "RAS tree", but if I configure anything like what Ip addresses the clients should get, I can't click apply or OK. Nothing happens.

In log I found this info:

18: The Secure Socket Tunneling Protocol service either could not read the SHA256 certificate hash from the registry or the data is invalid. To be valid, the SHA256 certificate hash must be of type REG_BINARY and 32 bytes in length. SSTP might not be able to retrieve the value from the registry due to some other system failure. The detailed error message is provided below. SSTP connections will not be accepted on this server. Correct the problem and try again.

The system cannot find the file specified.

20063: Remote Access Connection Manager failed to start because the Protocol engine [IKEv2] failed to initialize. The call timed out while waiting to acquire the transaction lock.

20192: A certificate could not be found. Connections that use the L2TP protocol over IPsec  require the installation of a machine certificate, also known as a computer  certificate. No L2TP calls will be accepted.

20171: Failed to apply IP Security on port VPN0-9 because of error: A certificate could not be found.  Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate..  No calls will be accepted to this port.
