Before downloading or purchasing Diagbox 9.129, you need to make sure your PC meets the requirements. The VMware version removes the Windows compatibility headache, but you still need sufficient hardware to run the virtual machine smoothly alongside your host OS.
Minimum System Requirements
- OS: Windows 10 or Windows 11 (64-bit) on the host machine
- RAM: 8 GB total (4 GB allocated to the VM, 4 GB for the host)
- CPU: Intel Core i5 (4th gen or newer) or AMD Ryzen 5 equivalent — virtualization must be enabled in BIOS (VT-x / AMD-V)
- Storage: 40 GB free disk space for the VM image (SSD strongly recommended)
- USB: At least 1 USB 2.0 or 3.0 port for the Lexia 3 / VCI interface
- Software: VMware Workstation Player 17 (free)
Recommended System Requirements
- RAM: 16 GB total (8 GB allocated to the VM)
- CPU: Intel Core i7 or Ryzen 7 (6 cores or more)
- Storage: SSD with at least 60 GB free — VM launch time is 3–4x faster on SSD vs HDD
- Display: 1920×1080 minimum for Diagbox’s interface to display correctly
VMware Configuration Settings
The pre-configured VM image ships with optimal settings, but if you need to adjust:
- RAM allocation: 4 GB minimum, 6–8 GB for best performance
- CPU cores: Allocate 2 cores minimum (4 preferred)
- USB Controller: Must be set to USB 2.0 compatibility mode for Lexia 3 recognition
- Network: NAT or Host-Only — no internet connection required for diagnostics
- Display: 3D acceleration off (causes instability in Diagbox)
Compatible VCI Interfaces
Diagbox 9.129 is compatible with the following Vehicle Communication Interfaces:
| Interface | Connection | Compatibility | Notes |
|---|---|---|---|
| Lexia 3 PP2000 | USB | All PSA vehicles | Most common, works with all Diagbox versions |
| Diagbox DiagPlug | USB/WiFi | CAN-bus vehicles | Newer interface for post-2012 models |
| Proxia | USB | All PSA vehicles | Dealer-grade hardware, highest reliability |
| J2534 PassThru | USB/OBD2 | CAN protocol only | Generic J2534 adapter, limited older vehicle coverage |
Enabling Virtualization in BIOS
VMware requires hardware virtualization support (VT-x on Intel, AMD-V on AMD). Most modern PCs have this enabled by default, but if VMware shows an error about virtualization, enter your BIOS/UEFI settings and enable “Intel Virtualization Technology” or “SVM Mode” under the CPU/Advanced settings menu.
