How to Fix “iqvw64e.sys Cannot Load on This Device” Error?

The ‘A driver cannot load on this device‘ error, often linked to the iqvw64e.sys file, occurs when the Intel Network Adapter Diagnostic Driver is blocked by Windows security features such as Core Isolation (Memory Integrity). This error can cause network connectivity issues, particularly after updates. If you’re encountering network connectivity problems, especially after recent Windows updates, we’ve outlined several solutions to help restore your network adapter’s functionality.

1. Update the Intel Network Adapter Diagnostic Driver Utility

This approach updates the crucial driver responsible for network connectivity, resolving compatibility issues and improving stability.

4. Update Windows to the Latest Version

Keeping Windows updated is essential for system stability and security. Issues like “iqvw64e.sys” often arise due to driver incompatibilities, which Microsoft frequently addresses through Windows Updates. These updates include essential security patches, bug fixes, and WHQL-certified drivers to ensure compatibility and performance.

1. Press Windows Key + I to open Settings.
2. Navigate to Windows Update (on the left menu).
3. Click Check for Updates and install any available updates.
4. Restart your computer to apply the updates.

5. Disabling Core Isolation (Caution Needed)

Core Isolation is a security feature in Windows that uses virtualization-based security to isolate critical parts of the operating system, adding an extra layer of protection against malware and other attacks. Memory Integrity, a component of Core Isolation, prevents malicious code from taking advantage of drivers and other low-level programs.

However, certain drivers, particularly older or less frequently updated ones like the Intel Network Adapter Diagnostic Driver, may not be compatible with Memory Integrity. This incompatibility can cause the drivers to fail to load, leading to hardware malfunctions or diagnostic errors.

Disabling Core Isolation and Memory Integrity might help by allowing the Intel Network Adapter Diagnostic Driver to load without obstruction.

1. Open Settings and navigate to Privacy & Security > Windows Security > Device Security.
2. Under Core Isolation, click Core Isolation Details.
3. Toggle off Memory Integrity.
4. Restart your computer.
