Many modern anti-cheat engines or game developers purposefully obfuscate memory (often called encryption). If you scan for the number you see on screen, Cheat Engine won't find it because the game is actually storing the value through an algorithmic formula.
: Before clicking "First Scan" or "Next Scan," ensure you have typed the number you are looking for into the Value box.
If you do not know the exact number you are looking for (like a visual health bar with no numbers), you cannot leave the box empty while using "Exact Value". Open the dropdown menu. Change it from Exact Value to Unknown initial value . If you do not know the exact number

This error usually appears during a "First Scan" or a "Next Scan" scan, stalling the process entirely. While the error message sounds vague, it typically indicates that Cheat Engine cannot read the memory address it is trying to scan, often due to security software interference, process protection, or corrupted temp files.

When Cheat Engine searches an application’s memory, it breaks the task into multiple execution threads. represents the primary worker thread tasked with initializing the memory sweep.
If Cheat Engine halts and demands that you "please fill something in," it means the scanner received an empty input vector, an unsupported character array, or was completely locked out of the memory space it attempted to parse. Primary Causes of "Thread 0" Errors
