SYMPTOMS
If you use the Extensions Manager to disable all extensions and control panels and then reinstall Office, Word, Microsoft Excel, or PowerPoint, you may notice the following behavior:  You have two copies of each extension and control panel that Office installs. One copy will be in the active folder and one one copy will be in a disabled folder. The Extensions Manager list shows multiple copies of the Office extensions and control panels. You receive the following error message when you manipulate Office extensions and control panels with the Extensions Manager:

An Extension could not be moved because a duplicate already exists in the target folder. Replace: ?





CAUSE
The Extensions Manager hides extensions and control panels from programs by moving them out of their respective active folders (active folders appear with an icon). The Microsoft Office Setup program searches the active folders to verify the existence of extensions and control panels. Therefore, the Setup program installs new copies of any extension not currently located in the active folders.



RESOLUTION
If you currently have this problem, delete any extra copies of extensions and control panels that appear within the inactive folders.

Office 98 Macintosh Edition
A complete installation of Office 98 Macintosh edition adds the following items:   Extensions                              Control Panels --  Microsoft Component Library             Microsoft Office Manager Microsoft Hyperlink Library Microsoft OLE Automation Microsoft OLE Library Microsoft RPC Runtime Library Microsoft Structured Storage

MS Library Folder: MS C++ Library (PPC) MS Configuration Lib PPC MS Container Lib (PPC) MS Internet Library (PPC) MS Preferences Library PPC MS Variant Lib (PPC)

Type Libraries: StandardOLETypes(PowerMac) Standard OLE Types 2 vba en olb (PowerMac)

Office 4.2.x
A complete installation of Office 4.2.x adds the following items:   Extensions                              Control Panels --

Apple Event Manager                    Microsoft Office Manager Genigraphics                           ODBC Setup Microsoft OLE Extension Office4.2x Update for Power Mac Shared Code Manager NOTE: The Setup program for Office 4.2.1b does not install the Office 4.2x Update for Power Mac extension. Office 4.2.1b owners who need the extension must install it manually.



MORE INFORMATION
When you use the Extensions Manager to disable an extension or control panel, the Extensions Manager moves that item to a temporary holding folder (this process makes the item inactive). The temporary holding folders, which appear in the active System folder, are listed in the following table.   This folder                   Is used this way ---

Extensions (Disabled)        Storage for disabled extensions Control Panels (Disabled)    Storage for disabled control panels System Extensions (Disabled) Storage for items on root of System Folder Programs designed to look into the active Extensions and Control Panels folders will no longer find those items.

NOTE: Many third-party extension and start up utilities have a similar behavior.
