Many Minecraft players face an unpleasant error when launching the game - a message appears in the launcher console:

Exception in thread “Client thread” java.lang.Error: IP Helper Library GetIpAddrTable function failed

Because of it the game does not start at all. The reason lies in Windows network configuration violation: ipconfig /all command entered in the command line does not display information about network adapters. Java does not find the connection and “crashes”.

It was not possible to fully investigate the problem, as the error appeared in one of the players of the Launcher, and not on the main system. However, a solution was found, albeit a bit non-standard.

Solution:

• Install the latest version of Java. This is a standard procedure, but it is still worth it to avoid possible conflicts.
• Create a new user in Windows. In an account created from scratch, Minecraft launches without any glitches. The error disappears.

This solution works on Windows 7, 10 and above. Instructions on how to create a new user are available on Microsoft's official website.

For those who have a deeper understanding of network settings and can fix the cause of the problem in the main account, it would be useful to share your experience - perhaps there will be a more elegant way to solve without creating a new user.
