Our host software is developed based on the Chuangxin Technology CANpro protocol analysis platform package. If the CAN port cannot be opened, the likely cause is that Chuangxin's package has been updated and needs manual replacement.
1. Download the CANpro protocol analysis platform bundled with the Chuangxin installer, locate the file directory
2. Replace the ControlCAN.dll in our host software with the one from that directory
