Preparation

0 of 5 steps
Remove third-party antivirus and anti-cheats Kaspersky, Avast, ESET and the like, plus FaceIT and Riot Vanguard, conflict with the loader. They must be uninstalled, not just paused.
  1. Open Settings → Apps → Installed apps (or Control Panel → Programs and Features).
  2. Uninstall any third-party antivirus (Kaspersky, Avast, AVG, ESET, 360, Malwarebytes, etc.). Pausing or disabling is not enough — the antivirus driver stays resident.
  3. Uninstall the FaceIT AC and Riot Vanguard anti-cheats if present — they block third-party software at the kernel level.
    • FaceIT is the CS2 anti-cheat, Vanguard is the Valorant one. If you don't play those games, they are safe to remove.
After removing an antivirus, restart the PC — some of its services only unload after a reboot.
A full walkthrough covering every case: How to turn off Windows Defender in Windows 11 and 10: fully or for one folder
Fully disable Windows Defender The #1 cause of “it won't launch”. Disable it for real: manually first, then remove it from startup, reboot, and finish it off with Defender Control.
  1. Step 1. Turn protection off by hand. Open Windows Security → Virus & threat protection → Manage settings and switch every toggle off:
    • Real-time protection — Off.
    • Cloud-delivered protection — Off.
    • Automatic sample submission — Off.
    • Tamper Protection — Off. Turn this one off first, otherwise the others switch themselves back on.
  2. Step 2. Disable reputation-based protection. In Windows Security → App & browser control → Reputation-based protection → Settings, turn everything off (SmartScreen, potentially-unwanted-app blocking).
  3. Step 3. Remove Defender from startup. Open Task Manager (Ctrl+Shift+Esc) → Startup apps tab, find Windows Security notification icon and click Disable.
  4. Step 4. Restart your computer. This is mandatory — some Defender services only unload after a reboot.
  5. Step 5. Finish with Defender Control. Download Defender Control (archive password: r1xon), run it as administrator and click Disable Windows Defender — the tile turns red.
    • If your antivirus deletes the utility itself, protection is still active — go back to step 1. The file ships zipped on purpose so Defender can't wipe it before it's disabled.
Don't skip steps 3–4. “I turned the toggles off but it didn't help” almost always means Defender came back after restart because it was left in startup.

Disable Core Isolation Memory Integrity blocks the driver from loading. Takes a minute to switch off.
  1. Open Windows Security → Device security → Core isolation details.
  2. Turn off Memory Integrity and restart the PC.

Disable Secure Boot Secure Boot stops the loader from starting. Check the status first, then disable it in BIOS if needed.
  1. Check the status: press Win + R, type msinfo32, and in System Summary find Secure Boot State. If it reads Off or Unsupported — you're set, skip the rest.
  2. If it's On — enter BIOS/UEFI (tap Del, F2 or F10 while the PC boots — depends on the motherboard).
  3. Find Boot or Security → Secure Boot and set it to Disabled. Save (usually F10) and reboot.
    • If Secure Boot is greyed out, set a Supervisor Password under Security first — that unlocks the option. You can remove the password afterwards.

Sync Windows time A wrong system clock breaks key authorization against the license server.
  1. Open Settings → Time & language → Date & time, enable Set time automatically and click Sync now.

Launch

0 of 4 steps
  1. Download the loader: open mason.orion-security.su/launcher (Russia and neighbouring countries) or mason.orion-security.pro/launcher (EU and Ukraine) and enter the key you received after payment.
  2. Run the downloaded file as administrator, pick your game in the loader window and click Run.
  3. Wait until the loader shows a check mark and closes, then launch the game yourself right away.

Problems & fixes

77
ESP draws enemies incorrectly: the box is shifted away from the enemy or vehicle
  1. Close the game.
  2. Set the display scale in Windows settings to 100% (guide).
  3. Launch the cheat and the game again.
What it looks like: screenshot.
ESP turns off after a while and won't turn back on
  1. Close the game.
  2. Disable the Windows paging file (guide).
  3. Restart your computer.
  4. Run the cheat again following the instructions.
The cheat menu doesn't open in the game
Make sure your PC and the game are properly prepared:
  1. Restart your computer and disable Windows security services.
  2. Launch the game and set the window mode to Windowed in its settings: windowed with a frame, even if the game supports fullscreen. This is temporary.
  3. Close the game and download the latest loader from mason.orion-security.su/launcher (Russia and neighbouring countries) or mason.orion-security.pro/launcher (EU and Ukraine) using your key.
  4. In Windows search, type Settings and open Date & time.
  5. Turn on automatic time and automatic time zone. If they are already on, turn the toggles off and on again (screenshot).
  6. Be sure to sync the clock.
  7. Restart your router or modem.
  8. Launch again.
Failed to connect to the server
Your PC must have the correct time and time zone.
  1. In Windows search, type Settings and open Date & time.
  2. Turn on automatic time and automatic time zone. If they are already on, turn the toggles off and on again (screenshot).
  3. Be sure to sync the clock.
  4. Start the loader again and inject.
If syncing the time didn't help, launch through a VPN:
  1. Install any VPN and connect to any CIS country, ideally Russia.
  2. Once the VPN is working, launch again.
  3. Don't turn off the VPN after launching the cheat or while playing.
What the error looks like: screenshot.
The loader only works through a VPN (Ukraine, Europe)
Most likely you have the loader for Russia and neighbouring countries: from Ukraine and Europe it only connects through a VPN, and you would need the VPN on every launch. Download the loader for your region from mason.orion-security.pro/launcher (EU and Ukraine) — the Loader for EU and Ukraine button at the top of the page. It needs no VPN. The loader for Russia and neighbouring countries is at mason.orion-security.su/launcher.
The required WebView2 Runtime could not be found
  1. Download and install WebView2.
  2. Restart your computer.
  3. Run the cheat again following the instructions.
What the error looks like: screenshot.
Failed to load a driver
  1. Go back to the PC preparation steps at the start of the guide.
  2. Uninstall Faceit, Riot Vanguard and any similar programs.
  3. Empty the Recycle Bin and clear the Temp folder (how to clear Temp).
  4. Restart your computer.
  5. Run the cheat again.
What the error looks like: screenshot.
Failed to get ready Signal or Failed Signal
  1. Restart your computer.
  2. Repeat the launch following the instructions.
  3. When the loader closes by itself after a successful injection, launch the game right away.
  4. In the game's main menu, press Home to open the cheat menu. It appears in the top-left corner of the game window.
