It sounds like you are referring to a of DiagBox 7.02 (often labeled as “7.02 Plus” or “7.57”) from MHH Auto forum, specifically the “Page 1” update or first post.
- Virtual machine host (VMware Workstation/Player/ESXi) is commonly used to run older Windows versions required by DiagBox (often Windows 7/8/10). VMware provides isolated environment but adds layers where USB-to-Serial/OBD adapters must be passed through.
- USB passthrough: Critical for FTDI/Prolific/ELM or K-line/RS232 interfaces. Proper driver install order (host vs guest) and exclusive capture of the adapter by the guest are necessary.
- COM port mapping: Many adapters expose serial ports; ensuring VMware maps the physical COM to the guest OS COM port number expected by DiagBox is essential.
- Brick your BSI (Body Systems Interface) – resulting in a car that won't start.
- Improper DPF regeneration can melt the turbo.
- Changing VIN in the ECU is illegal in many countries.
- If Page 1 adds a new module list or faster detection, select the updated Page 1 entry and run “Scan All Modules.” Compare results pre/post update to confirm additional modules detected or corrected labels.
VMware Pre-Configured Image
- Host and guest: Use a stable VMware Workstation/Player or ESXi and create a dedicated Windows 7/10 VM with sufficient RAM (4–8 GB) and fixed virtual HDD.
- Snapshot baseline: Install OS, utilities, and take a baseline snapshot before DiagBox installation.
- Drivers: Install correct FTDI drivers in guest; if using Prolific clones, obtain compatible drivers and disable host capture of device.
- USB passthrough: Connect VCI, ensure VMware maps it directly to guest (remove from host). Confirm COM port number in Device Manager matches DiagBox settings.
- Install DiagBox: Run the 7.02 or 7.57 installer in the VM (prefer the version known to support your target vehicles). Install VC redistributables if needed.
- Activation: Use activation method that persists across VM changes (bind to VM UUID or use a license file designed for VM use). After any major VM hardware change, revalidate license.
- Updates: Apply MHH Auto or vendor-provided update carefully — back up the DiagBox directory and registry, and test on non-critical vehicles.
- Testing: Verify communication for basic diagnostics, then test advanced features (programming/coding) with a non-production module first.
- Maintain isolation: Avoid snapshots that rollback license-relevant hardware IDs; document any changes.
