Mac OS 8: Clean Install Message

If I select a clean installation in the Mac OS 8 Installer and switch to the Finder and back, I get the message "The clean install option was reverted to an update install. Please click Options if you wish to change this option."

Since the clean installation option was added to the Installer application (not the "Install Mac OS 8" application), the Installer has always reverted back to a standard installation if the user changed the destination volume or switched to another application.

Prior to Mac OS 7.6, the Installer just silently reverted and left it up to the user to notice that the Clean Install button had changed to Install. For Mac OS 7.6, Apple decided to alert the user to this change by presenting the alert you see.

The easiest way to enable the clean installation option again is to click Options in the Installer application (not the "Install Mac OS 8" application), and choose Install New System Folder. If the Installer is quit and then restarted, using the "Install Mac OS 8" application, the clean installation option will be enabled once again.
