Mac OS 9: Use Disk First Aid 8.5.3 and Drive Setup 1.8.1

I am trying to launch Disk First Aid and Drive Setup under Mac OS 9, but I keep getting an error message that "The application program cannot be launched because it cannot be run on this computer."
If you attempt to launch a version of Disk First Aid or Drive Setup that is older than the version included with Mac OS 9 you will receive this error message. The version of Disk First Aid included with Mac OS 9 is 8.5.4. The version of Drive Setup included with Mac OS 9 is 1.8.1.

These applications are installed in the Utilities folder of the same drive as the Mac OS 9 System Folder. If you cannot locate these versions or newer versions of these utilities, you can custom install Disk First Aid and Drive Setup from the Mac OS 9 installer.
