2. Create databases in PostgreSQL: diiis and worlds.
3. Change you account and password in database.Account.config and database.Worlds.conifg.
4. Restore worlds.backup to worlds database.
5. Compile by VS 2019/2022.
6. [Skip this stage for local game] Copy the config.ini file to the server folder (It overwrites the default settings):
   • Update the parameter entries with your IP record on the network: BindIP and PublicIP.
7. Launch wait until server start, it creates a hierarchy.

Prepare Client

Do this for each client connecting to the server.

1. Get supported client Diablo 3.

2. Install certificate bnetserver.p12, password - 123 (the game verifies the CA root certificates).

3. Setting up redirects client to your server:

   Method #1 - Hosts

   Add redirects to the hosts file (%WinDir%\System32\drivers\etc\hosts):
   127.0.0.1 us.actual.battle.net
127.0.0.1 eu.actual.battle.net

   !After the modification the official Battle.Net application will not be able to connect to the server!

   Method #2 - Modify main executable file

   // Find null-terminated string enum and rewrite with HexEditor to your IP server.
   eu.actual.battle.net/
   us.actual.battle.net/
   cn.actual.battle.net/
   kr.actual.battle.net/

4. Launch client (x64 or x86) with arguments "Diablo III64.exe" -launch

5. Login to the game using your credentials.

6. [Skip this stage for local game] After that, when creating a game (in client), indicate the creation of a public game. Other players, when connecting, must also indicate a public game, and at the start they will connect to you.

7. You're in the game world!
