Trainz CDP Extractor: A Verified Guide
| Error Message | Cause | Verified Solution |
| :--- | :--- | :--- |
| "Invalid CDP Header" | The file is actually a .CDP2 (Trainz 2019+ encrypted) or a renamed .RAR file. | Use CDP Archiver (verified for TRS19) instead of the standard extractor. |
| "Access Violation at address..." | The CDP is damaged or partially downloaded. | Run the extractor as Administrator. If that fails, the CDP is corrupted. Use TrainzUtil validate via Command Line. |
| "Missing zlib.dll" | You downloaded a standalone EXE without dependencies. | The verified pack includes a runtime folder. Re-download from the official forum thread. |

: Choose your destination folder. The tool will recreate the original KUID folder structure automatically. Why use this over Content Manager?
Pro Tip: Do not place extracted assets directly into Trainz Editing folder unless you plan to commit them via Content Manager. Manually moving raw files can break database references.
