For professionals, reverse engineers, and legacy software users, running a for Code 39 on Windows 11 has become a necessity. Physical dongles break, get lost, or are no longer manufactured. Enter software emulation: a virtual USB device that mimics the physical dongle.
If Windows 11 still refuses to load the driver due to Virtualization-Based Security, you can turn it off via the registry. Press Win + R , type regedit , and hit Enter. Navigate to the following key:
Virtual USB Multikey (often referred to as Multikey) is a device driver emulator. It allows software that relies on Sentinel HASP, Hardlock, or other hardware keys to believe a dongle is plugged into the computer. Understanding Error Code 39
Install the updated driver using an elevated Command Prompt or the provided install.cmd script run as an Administrator. Method 4: Clean Reinstallation via Device Manager
Make sure the correct .reg dongle data file has been merged into the registry. Also verify that the software is looking for the same type of dongle that your emulator is providing (e.g., HASP HL vs. Sentinel SuperPro). Some applications require the original Sentinel drivers to be present and running; you can check their status in under Sentinel LDK License Manager or Sentinel Protection Server .

The most common and immediate workaround to force Windows 11 to load the emulator driver is turning off Memory Integrity.
Test thoroughly in a non-production environment first. Always keep a backup physical dongle if possible. And respect the software licenses that made the original tools possible.
If Method 1 does not work, you may need to disable the requirement for signed drivers to allow the Virtual USB Multikey to load. Go to . Under Advanced startup , click Restart now .
You can use bcdedit /set nointegritychecks ON in an elevated command prompt to permanently disable it, but this exposes your system to malicious drivers. If Windows 11 still refuses to load the
Click in the top menu bar of Device Manager, select Add legacy hardware , and manually browse to the folder containing your 64-bit multikey.inf and multikey.sys files to reinstall.
SafeNet’s own software‑only licensing option that does not require a physical dongle. It is supported natively on Windows 11. However, it requires the software vendor to enable this mode, which is not always available for legacy applications.
Hold down the Shift key while clicking in the Windows Start Menu.
Windows 11 requires all kernel-mode drivers to be digitally signed by Microsoft or a trusted authority. Unofficial MultiKey releases lack these certificates. It allows software that relies on Sentinel HASP,
To ensure a successful implementation of Virtual USB Multikey Code 39 on Windows 11, consider the following best practices:
The name "Code 39" in a user's search query might refer to the common Windows Device Manager error of the same number: . This error message often appears when a driver is corrupted, missing, or has a signature issue.
