VBS (like Memory Integrity) in Windows 11 can block low-level drivers. Search for in the Windows search bar. Turn Off Memory Integrity. Restart the computer. 3. Alternative Solutions (Using FTK Imager Lite)
The software fails to start this driver due to three main problems:
Kernel drivers are a common target for rootkits. Many security products—especially McAfee, Symantec, CrowdStrike, or modern Windows Defender—will automatically block the installation of unknown or rarely seen drivers, even if they are legitimate.
