If your Windows username contains non-ASCII characters (e.g., "é"), the default save path may fail. Go to Settings > Scan Settings and set a custom folder (e.g., C:\CEScans ) that is not protected by Windows.

: If you are trying to scan a 64-bit application with the 32-bit version of Cheat Engine ( cheatengine-i386.exe ), you will often see scan errors. Switch to cheatengine-x86_64.exe found in the Cheat Engine installation folder .

: If you get a "no readable memory" variation, your scan bounds might be too wide. Try setting the Stop address to 7FFFFFFFFFFF instead of the default to avoid scanning non-existent virtual memory.
