Hello, The `Append Error Details.vi` uses a `Carriage Return` constant. On Windows the last line of the error message will be overwritten. <img width="989" height="426" alt="Image" src="https://github.com/user-attachments/assets/e7c290dd-008a-422f-bb61-77cb398dc2d9" /> Solution: Replace `Carriage Return` with `End Of Line` constant.
