Your DullWave – XDefiant license key was emailed to you the second your payment cleared - it's also waiting in My Account → Orders. This guide takes you from that key to your first launch.

1. Prepare Windows

DullWave loads at a low level, so a clean environment is the difference between a smooth launch and a crash. Do all of this before you download anything:

Disable Windows Defender real-time protection, SmartScreen and Secure Boot.
Enable Hyper-V (search "Turn Windows features on or off" → tick Hyper-V).
Uninstall every third-party antivirus, plus FACEIT AC, ESEA and Riot Vanguard - they hard-block the loader.

⚠️

Never open the loader while XDefiant is already running - injecting into a live game is the fastest way to get flagged. Close the game first, every time.

2. Redeem & download

Head to the DullWave website, sign in (or register), and enter your license key to unlock your subscription.

Download the loader from your DullWave dashboard and drop it in its own folder that your antivirus has an exclusion for.

3. Launch sequence

With XDefiant fully closed, run the loader as administrator and sign in.

Wait for full initialization - on success you'll hear a beep and the loader closes itself.

Start XDefiant, then press F2 to inject.

Open the in-game menu with HOME and configure your build.

First run of the day? Check our status page - if DullWave for XDefiant shows Updating, wait for the green Undetected badge before you load.

Troubleshooting

"Failed to send GET request: SSL connect error" - your ISP is blocking the auth server - connect through a VPN and relaunch.
Stuck on mem_ctx - uninstall FACEIT / ESEA, disable Core Isolation (Windows Security → Device security → Memory integrity), then reboot.
Blue screen on mem_ctx - your Windows build isn't supported - move to one of: Win 10 / 11 (24H2).
Loader closes with no beep - run it as administrator and confirm your AV exclusion is actually applied (Defender loves to silently re-enable).

Still stuck?
