Restart your PC and try launching VALORANT<\/em> afterward.<\/li> <\/ol> If you don\u2019t see the Memory Integrity option in Windows settings, you likely don\u2019t have Virtualization enabled in your system\u2019s BIOS. To check this, you need to open up your system\u2019s BIOS settings and enable the setting. The steps depend on the motherboard manufacturer, so we recommend searching \u201cHow to turn on virtualization for <insert your motherboard manufacturer name> PCs\u201d on the web. You should find the manual to enable virtualization for the manufacturer on their official website. The BIOS contains sensitive settings; make sure you know what you\u2019re doing before tampering with the default values. <\/p> If enabling Virtualization doesn\u2019t work either, make sure your system is up to date with the latest OS and driver versions.<\/p> Then again, it\u2019s unclear how Vanguard works to mandate HVCI for VALORANT<\/em>. My Windows 11 PC (upgraded from Windows 10) runs the game without Memory Integrity enabled, but I\u2019ve never faced the error in question. I do, however, have other security requirements enabled and don\u2019t use any third-party applications with VALORANT<\/em>, which is probably why the error hasn\u2019t popped up for me yet.<\/p>
