📌 IMPORTANT PURCHASE NOTICE – MUST READ BEFORE BUYING
To ensure a smooth setup and avoid any installation compliance issues, please review the following technical requirements for our professional diagnostic tool:
- Antivirus Compatibility (False Positives): > Because most aftermarket diagnostic software utilizes deep-system emulation to interface directly with your vehicle’s ECU, strict security tools (like Windows Defender) will frequently flag it as a threat. This is a standard false positive. For successful installation, the software must be added to your antivirus "Exclusion List" or the antivirus temporarily disabled during use. If you are uncomfortable with this standard protocol, please consider alternative options.
- Pre-Installed Software Activation Required: > If your package includes a pre-installed hard drive (HDD/SSD), the system and diagnostic software are securely locked for transit and require activation before first use. Upon receiving your package, please contact our support team immediately to get remote activation service. It is not defective; it simply requires a 5-minute initial unlock.
- HDD/SSD Compatibility & Restrictions (Except SKU: DS036): > Please note that ALL our software hard drives are designed as internal drives and CANNOT be used via a external USB enclosure, with the sole exception of SKU: DS036(Alldat* software). Before purchasing, please ensure the physical size and interface (e.g., 2.5" SATA) of our drive are fully compatible with your laptop's internal slot. If you are unsure about compatibility, please contact our customer support before buying.
- Pre-installed software HDD/SSD Warranty Void Policy: > Our pre-installed software contains encrypted configurations. Any attempt to duplicate, clone, or copy the files from our hard drive to another device will permanently lock the software and instantly VOID your product warranty. We do not provide after-sales support or refunds for drives that have been privately copied.
- Professional Remote Tech Support (Optional & Secure): > Automotive diagnostic software setup can be complex. We offer 100% free, secure remote technical assistance via TeamViewer to help you configure the system. This service is entirely optional. We respect your data privacy and will only perform necessary software configurations with your permission.
