Install and play


- Extract everything: unpack the complete ZIP into its own folder. Do not run it inside the archive or scatter its files into your SBPE or game folder.

- Open the launcher: first run SetupLauncher.cmd to check or install the runtime, then open the top-level Starbreak.EventLauncher.exe.

- Let it update: sign-in is temporarily unavailable during updates. Wait for downloading, verification and restart. Existing launchers normally update automatically.

- Choose where to play: select Event or Formal Test, then the United States, Japan or Beijing. Try a region with a stable connection and lower in-game latency. Production is not open yet.

- Choose launch mode: use Direct launch without plugins. For SBPE, select your SBPE root folder containing config.ini and loader.py.

- Sign in and play: use your account for the selected service, or choose Register for a new account. Pick your launch mode before signing in; the launcher uses that selection.

Keep the launcher folder intact. You may create a desktop shortcut to the top-level EXE; do not move the EXE out on its own.


Need a hand?


Old launcher says Guangzhou and cannot connect?

The old Guangzhou server is offline. Try Check for updates first. If that launcher cannot update itself, download the current player launcher above into a new folder. Keep your old folder for now.


SBPE launch fails?

Try Direct launch first. If that works, check the chosen SBPE folder and confirm SBPE itself can launch the game. Select the root folder, not plugins.


Download blocked or flagged?

Save a screenshot and send it to us on Discord. For the launcher downloaded from this site, whitelist the launcher/SBPE folders, then restore quarantined files or extract the download again.


Update progress seems stuck?

Verification and installation can take time. If Retry update appears, try again. If it keeps failing, share the launcher version, region and error screenshot. Do not send your password.


Runtime setup: using SetupLauncher

After extracting everything, double-click SetupLauncher.cmd. It checks for x64 .NET 10 Desktop Runtime. If it is already installed, setup reports that it is ready. Otherwise it downloads the Microsoft installer. Keep SetupLauncher.ps1 beside the CMD file.


- You need the Desktop Runtime, not the full SDK. .NET 8, .NET 9, x86 runtimes, or ASP.NET Core alone do not replace the x64 .NET 10 Desktop Runtime required here.

- Setup checks the installer’s SHA-512 and publisher signature. If Windows asks for permission, verify that the publisher is Microsoft Corporation. Restart manually if the installer requests it, then reopen the launcher.

- If downloading or installation fails, keep the exact error. You can also use the Microsoft .NET 10 download page (https://dotnet.microsoft.com/download/dotnet/10.0): under .NET Desktop Runtime, choose Windows x64, install it and reopen the launcher.

- Once the runtime is ready, open Starbreak.EventLauncher.exe. Setup is only needed when checking or installing dependencies.

Runtime installation may request Windows permission. The helper’s temporary PowerShell execution policy affects its child process only. It does not save a system policy, change antivirus settings, or run system repairs.


Antivirus blocking the launcher?

If your antivirus blocks the launcher or SBPE, save a screenshot of the alert and send it to us on Discord below.


- Make sure you downloaded the multiplayer launcher from this website.

- Add the extracted launcher folder to your antivirus trusted list, whitelist or exclusions. If you launch with SBPE, add your own SBPE folder as well.

- If a file was quarantined, restore it from quarantine. You can also add the folder to the whitelist and extract the download again, then run SetupLauncher.cmd and Starbreak.EventLauncher.exe.

If Windows shows “Windows protected your PC,” choose “More info,” then “Run anyway.” If you cannot find the setting, send us a screenshot on Discord and we will help.
