What does the error message+ "Cannot find .hlp or .idx files" mean?

Running the wrong command causes this error. Usually you will see these error messages if you select the .exe command instead of the .bat command. For example, to adjust a TDS540, the directory is TDS500.ADJ. The correct command is ADJ500.BAT. If you select the TDS500.exe, you will see this error message. This information is in the readme file on the disk.
