Cheat Engine Scan Error Thread 0 Please Fill Something In 100 May 2026

Then click First Scan again.

Why this works: CE requires a comparison baseline. "Unknown initial value" tells CE to scan all memory without a specific number. Blank tells CE nothing.

If you have filled in the value box correctly and selected the correct scan type, but still receive the error, consider these possibilities:

The most common cause is clicking "First Scan" or "Next Scan" when the Value text box is completely empty, or when it contains non-numeric characters for a numeric scan type (e.g., typing "abc" while scanning for 4-byte integers). Then click First Scan again

Different scan types require different input fields:

| Scan Type | What you must fill | |-----------|--------------------| | Exact Value | Single numeric or text value | | Value between | Two values: "Value 1" and "Value 2" | | Bigger than... | One value in the "Value" field | | Smaller than... | One value in the "Value" field | | Grouped | Pattern like 4:100 8:200 (address:value pairs) | Why this works: CE requires a comparison baseline

If you chose "Value between" but only filled "Value 1" (leaving "Value 2" blank), you will get the Thread 0 error.

Fix: Either fill both boxes or change scan type to "Exact Value." but still receive the error

Some script-heavy tables include auto-run LUA that clears the value box after each scan. If the script runs at the wrong moment, the scanner thread receives empty data.
