2. Disable Driver Signature Enforcement (Temporarily)

On Windows 10/11 x64, you cannot permanently install unsigned legacy drivers without a special boot. For the initial install, you must disable enforcement.

How to do it:

  1. Hold Shift and click Restart from the Start menu.
  2. Go to Troubleshoot > Advanced Options > Startup Settings.
  3. Click Restart.
  4. Press 7 or F7 to select “Disable driver signature enforcement.”

Warning: This setting resets after a normal reboot. You will need to repeat this step if you reinstall drivers later.

Short story: Autokent MVci — Multi Driver x64 Install

The installer hummed to life under the blue glow of Marko’s laptop. He had spent the late afternoon digging through forums for the elusive "Autokent MVCI Multi Driver x64" — a piece of software rumored to bridge old diagnostic hardware with modern 64-bit systems. In the thread comments people traded versions like contraband, warnings threaded with hope. He'd learned to move carefully: back up, disable drivers, set system restore points — rituals for modern alchemists. Autokent MVCI Multi Driver X64 is a specialized

Marko clicked Run. A compact wizard window opened, its progress bar an unpromising sliver. The first sign warned him: unsigned driver. He breathed steady; he'd signed the machine for test builds before. He chose the custom install, unchecking bundled utilities that smelled of telemetry. The driver package unpacked into a tidy folder. An INF file sat at the center like a map.

At step two the machine protested — "Windows blocked this driver" — an old protectiveness reasserting itself. He toggled the advanced boot option, rebooted into the mode that allowed unsigned drivers, and returned to the task. Each reboot felt like a tiny pact with the unknown.

When the hardware was plugged in — a compact MVCI dongle that still smelled faintly of solder flux — the device manager flickered a yellow triangle, then steadied into a new COM port number. Marko opened the diagnostic suite. The application greeted him with a blank slate and a quiet promise: detect vehicle.

On his workbench, an aging sedan exhaled as if relieved. The software fetched an ECU handshake, the dongle translated the binary like a seasoned interpreter. Data flowed: RPM, coolant temp, VIN. Marko watched the live stream of numbers and lines, a pulse finally read by tools that had not understood one another before.

Not everything worked on the first pass. A baud rate mismatch threw a stubborn timeout. He adjusted settings, toggled protocols, and—after a patient minute—saw a cascade of DTC codes. The little triumph tasted like victory and a reminder: software can resurrect hardware, but understanding is the true bridge.

As night deepened, Marko wrote notes: which driver version matched which Windows build, which tweaks disabled excessive logging, which COM port quirks appeared after sleep. He bundled them into a short README, the sort of thing he'd wished had existed when he'd started. Before closing the laptop he saved the restore point and re-enabled driver signature enforcement; he didn't want casual danger to outstay its welcome. Hold Shift and click Restart from the Start menu

Outside, the streetlights gathered like watchful eyes. Inside, a small LED on the MVCI dongle blinked steadily — a tiny heartbeat returning an old machine to conversation. Marko leaned back and imagined the cars that would speak more clearly now, mechanics who would gain a few more minutes of certainty, hobbyists who would trade frustration for curiosity. The install had been more than a setup; it had been a reconciliation between eras.

He shut the lid, the laptop's glow dimming. Tomorrow he would upload the README to the forum, paste the steps, and sign off with a single sentence: "Worked for me — here's how." Somewhere in a threaded corner, a reply would light up, another user would read, and the chain of shared fixes would inch onward. For now, the room hummed, the dongle blinked, and an old sedan on the lift awaited its next conversation.

Here’s a step-by-step guide for installing the AutoKent MVCI Multi-Driver (x64) on a Windows 64-bit system.
This driver is commonly used with MVCI (Multi-Vehicle Communication Interface) J2534 diagnostic tools for vehicles like Toyota, Lexus, Scion, etc.

Pre-Installation Preparation

Do not rush. 90% of failed installations occur because users skip these steps.

1. Verify Your Hardware Revision

Autokent clones exist in two main versions:

  • Rev A (Old): Uses a FTDI chip. Easy to install.
  • Rev B/C (Modern): Uses a custom USB controller. This requires the “Multi Driver.”

Check the sticker on the back or the PCB color. If it is green with a large main chip, you likely need the multi-driver.

Option A – Permanent (for testing/development only)

  1. Open Command Prompt as Admin
  2. Run: 
    bcdedit /set testsigning on
  3. Restart PC – you’ll see “Test Mode” watermark.
