Look In list must contain valid files or folders, separated by semicolons.
This error generally occurs when the directory or files listed in the Look in list contain characters that are not valid.
To correct this error
- Use the Look In dialog box to browse to the directory or file name to search rather than typing in the path or file name. You can access the Look In dialog box by choosing the ellipsis button next to the Look in list.
