Launcher utility to help start battle.net games with the steam overlay.

Official page http://madalien.com/stuff/bnetlauncher/


This application is intended to facilitate the launch of battle.net games from steam with overlay while still being auto logged in by the battle.net client.

Note: If the Battle.net client isn't running when starting the game it will be closed as soon as the game starts, otherwise it will be left running.

Howto Use

  1. Extract the included exe to any location you want (ex: steam folder)
  2. Add the exe to steam as a non-steam game shortcut
  3. On the shortcut properties add one of the following parameters:
code game
wow World of Warcraft
d3 Diablo 3
hs Heartstone
ow Overwatch
sc2 Starcraft 2
hots Heroes of the Storm
scr Starcraft Remastered
dst2 Destiny 2 (Overlay will not work!!! See notes bellow)
codbo4 Call of Duty: Black Ops 4

the result should look something like this: "G:\Steam\bnetlauncher.exe" wow

Note: Any parameter not on the list will just show an error, to ignore and continue -i can be added after the game parameter so it looks like: bnetlauncher.exe my_parameter -i

Destiny 2: Bungie has decided to implement anti-cheat mechanisms that also cause most overlays to not work as expected. See https://www.bungie.net/en/Help/Article/46101 for more information. If you need SteamController functionality https://alia5.github.io/GloSC/ is currently the best option.

Optional: In case of problems logging can be enabled by creating a enablelog.txt file inside "%localappdata%\madalien.com\bnetlauncher\", you can open the location by pasting the path into explorer or the run dialog in windows (WinKey+R)

Known Issues

  • Destiny 2 will not have Steam Overlay or any associate features when using bnetlauncher. This is intended by Bungie and cannot be resolved. Steam Input users can use https://alia5.github.io/GloSC/
  • Enabling multiple instances of battle.net client in it's options will break bnetlauncher functionality.
  • Users of MSI Afterburner, Fraps and other overlay software might experience crashes do to incompatibility with their own overlay and steam's, to solve the issue disable the 3rd party application overlay.
  • The game, bnetlauncher and steam must all have the same running permissions to work properly, this means if one of them is running has Administrator/Elevated Permissions, then all of them must also be run has Administrator/Elevated Permissions.
  • It's not possible to launch PTR versions of games, bnetlauncher uses battle.net client URI handler to start the games, which does not support the PTR versions. I haven't found a solution for this.
  • If bnetlauncher is used to start multiple games at the same time the last ones to launch will not be automaticly signed in.
  • Starting multiple copies of Startcraft Remastered may cause bnetlauncher to show an error since the game only allows one instance to be run at the same time.
  • Users of the 1.5 beta series will need to delete the "%localappdata%\madalien.com\Battle.net Launcher for Steam" directory by hand.
  • There's no built in routine to clean up the log files if they pile up (logging is disabled by default)
  • On close battle.net client will leave a "ghost" tray icon after being closed by bnetlauncher, moving the mouse over it will make it disappear.
