The error message "Scan error: thread 0: Please fill something in 100" typically occurs in Cheat Engine when the user attempts to perform a scan without providing a valid input value in the search box. In this context, "100" refers to the specific value you were likely trying to search for or a placeholder in the error string. Troubleshooting the Error
This error is generally a procedural issue rather than a software bug. Here are the most effective ways to resolve it: Check these:
Fill the Value Box: Ensure you have typed the number you want to find (e.g., your current in-game gold or health) into the "Value:" field before clicking First Scan.
Attach to Process: Confirm you have selected the correct game process by clicking the Computer Icon in the top-left corner. If Cheat Engine isn't attached to a running game, it cannot scan memory.
Check Scan Settings: If you are using a specialized scan type (like "All" or "Binary"), ensure the settings under Edit > Settings > Scan Settings are configured correctly. Sometimes enabling MEM_MAPPED can help if the values are stored in specific memory types.
Permissions and Space: Run Cheat Engine as an Administrator. Additionally, ensure you have at least 500MB of free disk space, as Cheat Engine creates temporary scan files that can cause "thread 0" errors if they cannot be written. Hex mode enabled
Antivirus Interference: Some antivirus or firewall software may block Cheat Engine's ability to read or write to memory, leading to access violations. Temporarily disabling these or adding an exception for Cheat Engine may resolve the issue. Common Scan Tips For users struggling with elusive values:
