Klar.gg is a Marvel Rivals cheat. Every user gets a custom build of the Klar loader.

Requirements

Intel or AMD, Windows 10 or 11 (20H2 or newer).

Windows Insider builds are not supported.

Uninstall all antiviruses.

Uninstall Kaspersky, McAfee, Norton and any other third-party antivirus. In Windows Security, go to Virus & threat protection > Virus & threat protection settings > Manage settings and turn the protections off as shown in this image.

Uninstall Riot Vanguard and FACEIT.

Both block Klar from loading.

Play in borderless mode.

Otherwise the game crashes on injection or mid-game.

Set up Klar.gg

Download the loader

Download the loader from klar.gg/loader.

Activate your key

Follow Klar's install guide. When you paste your key, remove any spaces and leave the Referral field empty. Your key is in your order email and on account.lmarket.net.

Load Klar before the game

Start the loader and load Klar before you launch Marvel Rivals.

Troubleshooting

If your error is not listed here, check that you followed every requirement and step above.

VGC.SYS

Uninstall Riot Vanguard. If you don't want to uninstall it, open Command Prompt as administrator, run sc stop vgk and load Klar again.

BEDAISY.SYS, EASYANTICHEAT.SYS or IJ4

You are injecting while the game is open. Load Klar before launching the game.

BHDRVS.SYS

Uninstall Norton antivirus.

I2

Something is blocking the injection. Uninstall all antiviruses, and disable Windows Defender and overlays. Core isolation (Memory Integrity) must be disabled.

I2 (-1073741637)

  1. Open Settings > Security > Device security.
  2. Turn off Memory Integrity.
  3. Restart your PC and check that Memory Integrity is still off.
  4. Start the loader again.

I2 (-1073741670)

FACEIT anti-cheat is installed on your PC. Uninstall it.

I2 (-1073740285) or a similar code

This is caused by the Windows 10/11 update of April 9, 2024. Go to Start > Settings > Windows Update > Update history > Uninstall updates and uninstall KB5036892 or KB5036893. The update names can differ, so uninstall all updates from April 9 and April 13, 2024, then disable Windows Update.

VCRUNTIME or MSVCP140.DLL

Install vc_redist.x64.exe.

M1 or Debug error 2

This is common on Windows Home. As a temporary fix, restart your PC before every injection. To fix it for good, reinstall Windows with the Pro edition.

Loader closes at 100%

Go to Windows Settings > Date and time, press Sync now, then inject Klar again.

Loader shows that you are banned

Restart your computer and log in again.

"Couldn't find a key"

This can happen when you activate a key for a cheat that is not working. Check the Klar status page before activating. Also remove all spaces from the pasted key and leave the Referral field empty.

"Disable real time protection"

Go to Virus & threat protection > Virus & threat protection settings > Manage settings and make sure it matches this image. If that doesn't work, use Defender Control to turn it off.

Infinite loading: "requesting updates"

  1. Open Network and Sharing Center, choose Ethernet > Properties and make sure the IPv6 protocol is selected.
  2. Download the loader again and retry.
  3. If it still doesn't work, download the loader again and use a VPN with an IP near Germany.

"Target didn't respond for 10 seconds"

The cheat is not updated yet. Check the Klar status page.

IJ1, IJ5 or IJ8

Follow the requirements above and restart your computer.

Error on Windows Insider

This error means Windows Insider is installed, which is not supported. Reinstall a normal version of Windows.

Blue screen of death

Open Command Prompt as administrator and run sfc /scannow. When it finishes, run DISM.exe /Online /Cleanup-image /Restorehealth, then restart your PC.
