Nimbus
Getting started

First run

What happens the first time you launch Nimbus, and what you should expect to see.

What the loader does on first launch

When you double-click Nimbus.exe for the first time, it:

  1. Creates a config/ folder next to itself with default settings.
  2. Reaches out to our version manifest at https://getnimbus.net/api/manifest/version to check whether your build is current.
  3. Downloads the matching payload DLL (about 11 MB) into payload/. This is the in-game overlay that gets injected after you sign in.
  4. Opens the loader UI. You'll see four tabs across the top: Launch, Anti-Cheat, Spoof, Settings.

The whole sequence takes 5–10 seconds on a fresh install.

Antivirus prompt

The first launch is the one Defender is most likely to flag. The reason is dull: SmartScreen has never seen this exact Nimbus.exe hash before. Once the hash has rolled around the SmartScreen reputation network for a few hours after each release, the prompts go away.

If you see a SmartScreen prompt, click More info then Run anyway.

If you see an actual Defender quarantine, see the Antivirus flagged it page.

Auto-update on launch

Every time you launch, the loader checks the version manifest and asks "is there a newer build?" If yes, you'll see a banner across the top of the loader UI:

A new build is available. Click here to install.

Old builds are the single biggest source of broken-inject tickets, and they elevate detection risk because anti-cheat already knows about the old payload's signatures. We strongly recommend you let the updater run.

You can opt out of auto-apply in Settings → Updates. You cannot opt out of being told a new build exists.
