Open the Run window ( Win + R ), type %appdata% , and delete any corresponding diagnostic data folders to prevent residual configuration conflicts.
This step activates the software:
Below is a comprehensive guide to installing the software and ensuring it stays activated. Pre-Installation Requirements Before you begin, ensure your system meets the DS150E recommended requirements Windows 10 (Pro or Home, 32/64-bit). At least 4GB RAM and 4GB of free disk space.
Before initiating the installation, ensure your Windows 10 environment meets the technical criteria necessary to handle both the software overhead and the USB driver bridge for your VCI (Vehicle Communication Interface) hardware. Dual-Core Intel or AMD CPU (2.0 GHz minimum) System Memory: Minimum 4 GB RAM
Hook the scanner up to a vehicle's OBD2 port or an external 12V power supply. The device requires vehicle power to flash firmware safely. Inside the Delphi program, go to > Hardware Setup . Select your matched COM Port and click Test . 2017 rev3 vfinal delphi cars fixed win10 install
: Once installed, connect your DS150E hardware via USB and use the software settings to update the device firmware for optimal vehicle coverage.
Windows Defender quarantined a crucial file Restore the file from quarantine; apply folder exclusions. "Main.exe - Application Error (0xc0000135)" Missing system runtime framework Turn on the Windows legacy .NET Framework 3.5 feature . VCI Hardware not detected via USB/Bluetooth Device Manager loaded the wrong serial COM driver
Go to Apps & Features to uninstall previous iterations of Autocom, Multidiag, or older Delphi builds. Navigate to C:\ProgramData , C:\Users\%username%\AppData\Roaming , and clear any residual folders associated with diagnostic tools. Phase 2: Directory Setup and File Extraction
Modern Windows 10 User Account Control (UAC) locks down security permissions in standard program folders. To bypass write-protection errors: Open the Run window ( Win + R
Return to your main Delphi instance prompt, click , select the newly modified FileActivation.xml , and let the configuration scripts finish loading.
If the software connects to your multiplexer but throws a "Firmware Mismatch" error, your hardware device requires an internal code update to match the vFinal database version:
Some users have reported that after installing the 2017 Rev3 vFinal software, the "Basic Settings" button (which should be located below "Real-time Data") is missing. Possible causes:
Once the software is open, go to Settings > Hardware Setup. Perform a "Test" to ensure the VCI is recognized. If the software shows a version mismatch, click "Update Firmware." Warning: Keep the VCI connected to both the laptop and a vehicle (for 12V power) during this process to avoid "bricking" the device. Final Optimization To keep your 2017 Rev3 VFinal stable on Windows 10: Exclude the Delphi folder from Windows Defender scans. At least 4GB RAM and 4GB of free disk space
the files into C:\Program Files or onto your Desktop.
Send your generated XML file to your software vendor or a trusted community activation thread to receive the modified version back. Step 4: Finalize the Activation Loop
If you use a DS150E or Multidiag OBD2 interface, this specific software revision is highly sought after because it patches crucial database stability bugs, resolves Bluetooth firmware disconnects, and extends legacy vehicle coverage. However, modern Windows 10 security updates aggressively block the diagnostic background services and keygen tools.
