‌

The game does not check for IPv6 in the system, and tries to open an IPv6 socket, but if there is no IPv6, it gets a WSA error 10047 WSAEAFNOSUPPORT.

Thus, the game does not handle the IPv6 socket open error and immediately crashes when the game is launched.

Below is the information that should be passed on to the developers:

10047 WSAEAFNOSUPPORT

Address family not supported by protocol family.

An address incompatible with the requested protocol was used.

All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM).

This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in sendto.
