Synthera DocsThis error indicates a conflict with Vanguard, FACEIT, or the required virtualization state.
⦁ Uninstall Riot Vanguard and FACEIT Anti-Cheat if either is installed.
⦁ Restart the PC.
⦁ Enter BIOS.
⦁ Find Intel Virtualization Technology, Intel VT-x, VMX, AMD-V, or SVM Mode.
⦁ Enable the applicable setting.

Note
The main documentation names Vanguard/FACEIT in the error but only gives virtualization as its solution. The uninstall steps above preserve the error’s explicit requirement while also retaining the supplied virtualization fix.
