If you absolutely need to run a Multikey-emulated device on Windows 11, here is the general process (as shared by legacy hardware communities):

Step 1 – Disable Integrity Checks (Temporarily)

Step 2 – Install Multikey Driver in a Compatible Mode Before committing to Multikey, consider: This is the

Step 3 – Resolve Code 39 Specifically
Code 39 appears when the driver’s DriverEntry routine fails or a previous driver instance is stuck. Solutions include:

Step 4 – Virtual USB Abstraction
Some advanced setups use a USB over IP redirection or a virtual machine (VM) with USB passthrough: run the dongle emulation inside a Windows 7 VM (where drivers load freely) and redirect the virtual USB device to Windows 11 via network. This bypasses native driver loading entirely.

Legacy automation software (CNC machines, medical analyzers, CAD/CAM from the early 2000s) often relies on physical parallel or USB dongles. When the original dongle fails (e.g., dead EEPROM) or is lost, and the vendor no longer exists, users turn to virtual emulation to keep critical systems running. The “Virtual USB” approach also allows running such software on modern laptops without physical dongles (e.g., for remote diagnostics).
