1. Install The Game (Unpack ISO image with WinRAR or Mount using DAEMON Tools Lite)
(Do not change the game folder name)

Right click the game folder -> properties and uncheck "read only" for all files. (already done in this version)

2. Install Reflection Network Launcher
3. Run Reflection Network Launcher, choose Diablo IV directory, point it at "Diablo IV.exe" and let the launcher verify the game files.
(if it takes too long, just close it and run again - you will be able to play right away)
4. Make free account here:

5. Play ;)

(if you see "queued" message, just logout and login again)

If you installed to other directory than default the launcher may not detect it and will start to download from scratch - just stop it and move your installed game to where the Launcher has started it's download.

Launcher is downloading the same files but it's very slow.

You may also run the game with command line: "Starter.exe -bypassgpudrivercheck Online.Host=login.d4reflection.org"

If mobs are not attacking, change difficulty in game or try again later.

PS. Updates are mostly being made on server-side without the need to download anything
