Created attachment 51464 [details] WINEDEBUG=+iphlpapi
Sorry for the noise, but yes Bruno, it looks like you're right, it doesn't seem related to winsock.
I found the issue:
DWORD WINAPI GetIpAddrTable(PMIB_IPADDRTABLE pIpAddrTable, PULONG pdwSize, BOOL bOrder)
the pIpAddrTable->table[i].wType parameter is not initialized (0) while programs expect a good value (see https://msdn.microsoft.com/en-us/library/windows/desktop/aa366845%28v=vs.85%...)
My workaround is to force it to 0x1 (it's enough to fix this app and PES2015 online, it seems, at least for the iphlpapi bug, now I'll see if there are any other issues). A better solution is appreciated.
