Preparation before use

  • Uninstall all antivirus programs, including Kaspersky, McAfee, Norton, and any third-party antiviruses.

Launching Klar

Download the loader.

After downloading the Klar loader, we recommend transferring it to a USB flash drive.

Using the Klar loader

To launch the loader, right-click on it and select "Run as administrator." This will launch the loader with the elevated privileges required to run cheats.

After opening the loader, you will be presented with a login form.

If you have never used the Klar loader before, you will need to register a new account.

To register an account, click "SIGN UP" under the "LOG IN" button and fill in the requested information.

After clicking "SIGN UP," your account will be created and linked to your current device using your HWID (hardware identifier). Your HWID can change when reinstalling Windows, enabling or disabling Secure Boot, or replacing hardware. If your HWID changes, you'll receive an "HWID mismatch" error and will need to open a support ticket to unlock your bootloader account's HWID.

You can activate license keys in the launcher in just a few simple steps:

After logging in, select the product for which you want to activate the key.

Enter the license key in the text field in the lower right corner of the launcher and click "START."

Your license key will begin to expire the moment you click "START."

Close the side window that appears and click the desired product again. The "START" button should now occupy the entire width of the side window. Click the button to launch the cheat.

  • If you use external spoofers from other providers, be sure to download them AFTER downloading Klar. Restart your computer if you want to reinject Klar; otherwise, you will need to reset the HWID of your downloader account.
