- Do not connect the C4b yet. Install the core Delphi Autocom software from the DVD or ISO image.
- Run the "Activator" (Patch). This bypasses the online serial check. Always disable your antivirus and Windows Defender temporarily—these tools flag patches as false positives.
- Install the C4b USB drivers. The correct driver for the C4b is different from the C5 or DS150. Ensure Windows recognizes it as "Delphi C4 VCI."
- Configure the software: Open the program, go to "Settings" > "Interface" > Select "C4 Serial" or "Bluetooth."
- Final Patch: Apply the "2021.11 time bomb fix" to prevent the software from asking for an update password after 30 days.
