Download DamnedX

One small installer. No admin rights, no extras bundled in. It keeps itself and the game client up to date.

DamnedXSetup.exe · 64-bit Windows 10 or 11 · about 30 MB

“Windows protected your PC”

Windows will probably show this blue box the first time you run the installer. It doesn't mean a virus was found. It means the file isn't signed with a paid Microsoft-approved certificate, so Windows hasn't seen it enough times yet to trust it. Most small games and open-source tools get the same warning.

  1. Click More info.
  2. Check the app name says DamnedXSetup.exe.
  3. Click Run anyway.

Never turn off your antivirus for DamnedX, and don't trust anyone who tells you to. If your antivirus blocks the file, tell us in Discord and we'll report it to the antivirus vendor as a false alarm.

Only download DamnedX from this page. The real file always comes from dl.damnedx.com. Anyone sending you an installer in DMs, or a link to another site, is not us.

What the installer does

  • Installs for your Windows user only, into %LOCALAPPDATA%\DamnedX. It never asks for admin rights.
  • Adds a Start menu entry, and a desktop shortcut if you tick the box.
  • Keeps your settings, saved logins and screenshots in %USERPROFILE%\.damnedx.
  • Each time it starts, it downloads the latest game client from dl.damnedx.com and checks the file's fingerprint before running it.
  • Uninstall from Settings → Apps → DamnedX. That removes the program and the downloaded client. Your settings folder stays unless you delete it.

DamnedX for Mac

Pick the download that matches your Mac. Not sure which one you have? Open the Apple menu → About This Mac. If it lists a Chip called Apple M1, M2, M3 or newer, get Apple Silicon. If it lists an Intel Processor, get Intel.

Apple Silicon

DamnedX-aarch64.dmg · M1 or newer · about 44 MB

Intel

DamnedX-x64.dmg · Intel Macs · about 34 MB

Open the downloaded .dmg and drag DamnedX into Applications. Then open it from Applications.

“Apple could not verify DamnedX”

The first time you open DamnedX, your Mac will probably refuse with this box. It doesn't mean malware was found. It means we haven't paid Apple to scan and approve (“notarize”) the app, so your Mac has nothing to check it against. Most small games and open-source tools that aren't on the App Store get the same message.

  1. Click Done. Don't move it to the Trash.
  2. Open System Settings → Privacy & Security and scroll down to Security.
  3. Check the message names DamnedX, then click Open Anyway.
  4. Confirm with your password or Touch ID, then click Open Anyway once more.

You only do this once. After that DamnedX opens like any other app. On macOS 14 or older you can instead right-click DamnedX in Applications, choose Open, then Open again.

Never turn off Gatekeeper or your Mac's other security settings for DamnedX, and never paste Terminal commands someone DMs you to “fix” it. The steps above are all it takes. If something else blocks the app, ask in Discord.

Only download DamnedX from this page. The real file always comes from dl.damnedx.com. Anyone sending you a .dmg in DMs, or a link to another site, is not us.

What the Mac app does

  • It's an ordinary app in your Applications folder. It installs nothing else, runs no background services and needs no special permissions.
  • Keeps your settings, saved logins and screenshots in ~/.damnedx in your home folder.
  • Each time it starts, it downloads the latest game client from dl.damnedx.com and checks the file's fingerprint before running it.
  • Comes with its own copy of Java, so you don't need to install anything else.
  • To uninstall, drag DamnedX from Applications to the Trash. Delete ~/.damnedx too if you want your settings gone.

Check the file yourself

You don't have to take our word for it.

1. Compare the fingerprint. This is the SHA-256 of the current installer:

9fb2287b98e1731565e84d3c2d3a1306d115d18778e433bf448643a8efb2c802

Open PowerShell in your Downloads folder and run:

Get-FileHash .\DamnedXSetup.exe

The Hash it prints should match the one above (upper or lower case doesn't matter). If it doesn't, delete the file and download it again from this page.

On a Mac, these are the SHA-256s of the two disk images:

DamnedX-aarch64.dmg db202ae4d3641ae4b02cf134850b45fa3c6c6ba8bfc7084f89d309bacd62d1cd DamnedX-x64.dmg 4e538852b7c6fc10d865e9f96fe4ef1c1a75f8806fcfdf3ee4ddfec7567db551

Open Terminal and run shasum -a 256 ~/Downloads/DamnedX-*.dmg to compare.

2. Scan it. See the VirusTotal report for this exact file, where around 70 antivirus engines have scanned it. On a Mac, you can drop the .dmg onto virustotal.com to scan it yourself.

3. Know what it's built on. DamnedX is a fork of RuneLite, the open-source Old School RuneScape client millions of players use. Our launcher is a fork of RuneLite's, and its source is public: the only changes are our name, icons and download address.
