Cable Not Found: If VCDS doesn't see your cable, go to Options -> Test. Ensure you are using a high-quality USB port and that the green LED on the cable is lit.
Windows 10/11 Issues: If the software crashes, try running it in "Compatibility Mode" for Windows 7 or check if your antivirus is blocking the VCDS.exe file.
Updates: If you have a genuine cable, you can usually upgrade to the latest version for free directly through the software.
