Cheat Engine Scan Error Thread 0 Please Fill Something In 100 New -

The neon glow of Alex’s monitor was the only light in the room as the clock struck 3:00 AM. He was so close. The "Infinite Health" address was buried somewhere in the code of Abyssal Reach, a game notorious for its crushing difficulty.

He opened Cheat Engine, attached the process, and hit 'First Scan.'

Suddenly, the progress bar turned blood-red. A dialogue box popped up with a message he’d never seen: "Scan Error: Thread 0 please fill something in 100 new."

"What the hell?" Alex muttered, clicking 'OK.' The box didn't close. Instead, a new window flickered to life—a hex editor displaying memory strings that shouldn't exist. 00 00 HELP 00 0000 00 FILL 00 00

The "100 new" wasn't a memory limit; it was a countdown. In the reflection of his screen, Alex saw a shadow standing in the corner of his room. Every time the value in Thread 0 ticked down, the shadow moved closer.

He realized with a jolt of terror that the "something" the error wanted wasn't a value or a byte. It was a trade. He frantically typed 999999 into the value field, desperate to break the loop, but the error flashed again, faster this time. "Thread 0: 50 new. Please fill something in."

The air in the room turned ice-cold. The shadow was now at his shoulder, its hand reaching for the keyboard. Alex didn't look back. He realized the game wasn't scanning his RAM anymore—it was scanning him.

"Scan error: thread 0: Please fill something in 100" in Cheat Engine typically occurs when the software expects a specific input value or configuration setting that has been left blank or is invalid for the current scan type.

Hi everyone,

I am currently trying to hack [Insert Game Name Here] using Cheat Engine [Insert CE Version, e.g., 7.5], but I am running into an error immediately when I try to start a new scan.

The Error: Every time I click "First Scan," I get the following error message in the scan window:

Scan Error: Thread 0: Please fill something in

What I have tried so far:

• I have restarted Cheat Engine and the game.
• I have tried running Cheat Engine as Administrator.
• I have tried both "4 Bytes" and "All" value types.
• I made sure the process list is populated (I selected the game process from the list).
• I am using the standard settings (Main scan type: Exact Value).

System Info:

• OS: [e.g., Windows 10 / Windows 11]
• Game Version: [Steam / GOG / Pirated (please specify)]
• Cheat Engine Version: [e.g., 7.5.1]

Has anyone encountered this specific error before? It seems like a UI bug or a configuration issue, but I can't figure out what field is "empty" since I have typed in a value to search for.

Any help would be greatly appreciated!

Troubleshooting Report: Cheat Engine Scan Error – “Thread 0 Please Fill Something In 100 New”

Report Date: 2026-04-12
Software: Cheat Engine (version 7.x or later)
Issue Category: Scan error / Memory scanning failure

100‑word paper

"Cheat Engine Scan Error: Thread 0 — Please Fill Something In" often appears when the scanner cannot read or access target process memory due to insufficient privileges, protected processes, or incorrect target selection. Common causes include running Cheat Engine without administrator rights, attaching to a 64‑bit process with a 32‑bit build, antivirus or anti-cheat protections blocking access, or selecting an invalid memory region. To resolve: run Cheat Engine as administrator, use the correct 32/64‑bit CE executable, disable interfering antivirus/anti‑cheat while testing in safe contexts, ensure the target process is selected correctly, and consult logs for specific read/write errors. Always avoid using Cheat Engine against online games with anti‑cheat—doing so risks bans.

Solution 5: Reinstall Cheat Engine

• Uninstall completely, delete C:\Program Files\Cheat Engine\ and %APPDATA%\Cheat Engine\.
• Download the latest stable version (not beta) from the official site.

Q2: Does this error harm my computer or game?

No. It’s a soft error within Cheat Engine. It does not crash the game or damage hardware.

Fix 2: Delete Hidden Spaces or Characters

Highlight the value box and press Ctrl+A (Select All), then Delete. Type your value again manually—do not paste from an external source.

If you must paste, first paste into Notepad, then copy from Notepad into Cheat Engine.

Fix 6: Run Cheat Engine as Administrator

Lack of permissions can confuse the scanning thread:

• Right-click cheatengine-x86_64.exe or cheatengine-i386.exe.
• Select Run as administrator.
• Re-attach to the target process.

1. The Primary Cause: Empty Input

The most common reason for this error is that the "Value" input box (located next to the "Scan" button) is empty or contains only spaces.

• The Fix: Ensure you type a number (e.g., 100) or text into the Value box before clicking First Scan.
• Note: If you are trying to search for "Unknown Initial Value," you must change the "Scan Type" dropdown to specifically say "Unknown initial value". If the scan type is set to "Exact Value" and you leave the box empty, the error will persist.

Solution 2: Clear Cheat Engine Configuration

1. Close Cheat Engine.
2. Delete or rename cheatengine-x86_64.exe.ini (and cheatengine-x86.exe.ini if using 32-bit).
   • Typically found in %APPDATA%\Cheat Engine\ or CE install folder.
3. Restart Cheat Engine – default settings will load.
