How to Set Up Diagbox 9.129 in VMware on Windows 10 and 11

The Diagbox 9.129 VMware virtual machine is the easiest way to run dealer-level PSA diagnostics on a modern Windows 10 or 11 PC. This step-by-step guide covers everything from installing VMware to your first successful vehicle connection.

What You Need Before Starting

• A Windows 10 or Windows 11 PC (64-bit)
• At least 8 GB RAM (16 GB recommended)
• 40+ GB free disk space (SSD strongly recommended)
• VMware Workstation Player 17 (free download from vmware.com)
• The Diagbox 9.129 VMware image file (.vmdk or .ova)
• A Lexia 3 PP2000 or DiagPlug VCI interface

Check the full Diagbox system requirements before proceeding.

Step 1 — Install VMware Workstation Player

Download VMware Workstation Player 17 from vmware.com (free for personal/non-commercial use). Run the installer with default settings. After installation, reboot your PC if prompted. If you see an error about virtualization not being enabled, you need to enable VT-x or AMD-V in your BIOS settings first.

Step 2 — Import the Diagbox VM Image

1. Extract the downloaded Diagbox 9.129 archive to a folder on your SSD (e.g., C:\VMs\Diagbox)
2. Open VMware Workstation Player
3. Click Open a Virtual Machine
4. Navigate to the extracted folder and select the .vmx or .ova file
5. Click Open — VMware imports the VM (takes 1–3 minutes)
6. If prompted about the VM being moved/copied, select “I Copied It”

Step 3 — Configure USB Passthrough

This step is critical for your Lexia 3 interface to work inside the VM:

1. Before starting the VM, go to Edit Virtual Machine Settings
2. Click on USB Controller
3. Ensure USB compatibility is set to USB 2.0 (not 3.0 — Lexia 3 uses USB 2.0)
4. Check “Automatically connect new USB devices”
5. Click OK to save

Step 4 — Start the Virtual Machine

1. Click Play Virtual Machine
2. Windows 7 will boot inside the VM window (takes 30–60 seconds on SSD)
3. Diagbox 9.129 launches automatically on the desktop — no additional setup required
4. If Windows asks about hardware detection on first boot, allow it to complete

Step 5 — Connect Your Lexia 3 Interface

1. Plug your Lexia 3 USB cable into your PC
2. VMware will detect the new USB device — in the VMware taskbar at the bottom, click the USB icon and select Connect (Disconnect from Host) to pass the interface into the VM
3. Windows inside the VM will install the Lexia 3 drivers automatically (first use only)
4. Wait for the driver installation to complete

Step 6 — First Diagnostic Session

1. Connect the other end of your Lexia 3 to the vehicle’s OBD2 port
2. Turn the vehicle ignition to position 2 (accessories on, engine off)
3. In Diagbox, click Diagnostics
4. Select your vehicle brand (Peugeot, Citroën, DS, or Opel)
5. Diagbox auto-detects the vehicle — confirm the vehicle details
6. Choose Full Scan to read fault codes from all modules
