| Cause | Explanation | Fix | |-------|-------------|-----| | Anti-cheat software | EAC, BattlEye, Vanguard block CE | Use kernel-mode debugging (advanced), or avoid protected games. | | Scanning too wide range | Scanning all memory (e.g., All Memory region) triggers errors | Change scan type to only the process’s main module (e.g., .exe/.text section) | | Memory type mismatch | Scanning for Float but the value is Double/4-byte | Correct the Value Type in Scan Settings | | Fast Scan misconfiguration | “Also scan read-only memory” unchecked when needed | Enable “Also scan read-only memory” | | Process has high integrity level | Running as admin vs. game as user | Run both Cheat Engine and the target process as Administrator | | Heap corruption / packed executable | Some regions are not pageable | Use “MEM_PRIVATE” filter in Memory Scan Options | | Virtual memory exhaustion | Too many scan results from previous scan | Clear scan results (New Scan) and use smaller start range | Disable conflicting tools
Many users see the number "100" in error logs or forum posts regarding this topic and get confused.
If the process is heavily protected, you may need a kernel-mode driver (DBVM) built into CE.
The "Cheat Engine scan error thread 0 please fill something in" is one of the most common but easiest errors to solve. With this 100-best guide, you have every possible fix at your fingertips.
