5.00 5.50 6.00

MS-DOS

= SUMMARY =

When attempting to execute a DOS command in Word 5.00 from the Library Run command menu, DOS will return the error message “Incorrect DOS version” to Word if multiple versions of COMMAND.COM are found on the disk.

In Word version 5.50, this error message will be returned from DOS when attempting to execute a DOS command from the File DOS Commands menu (ALT, F, D).

Check for a DOS COMMAND.COM file in the Word directory.

= MORE INFORMATION =

You can detect which command processor (COMMAND.COM) is being invoked by typing SET at the DOS prompt.

It is important that the DOS command processor is the same version as the DOS system files. To check the version of the system files, type VER at the DOS prompt. To check the version of the command processor, type COMMAND at the DOS prompt. Also make sure that the brand names are the same (for example, IBM PC-DOS, Compaq DOS, etc.).

If the versions or brands do not match, it is highly recommended that you delete all the extra COMMAND.COM files and re-SYS the drive with a version of DOS that is compatible with the computer.

Below are the steps to reinstall DOS on the hard disk:

  After booting the computer from a DOS-bootable disk, type the following: SYS C: (Where C is the boot disk).   Copy COMMAND.COM to Drive C by typing COPY COMMAND.COM C: at the DOS prompt. It is advisable to have only one command processor on the drive to avoid any subsequent problems of this type.
