Customizing Removal Behavior
When you upgrade to Office 2003 Editions, the Removal Wizard (Offcln.exe) removes unnecessary or obsolete components from previously installed versions of Office and related applications. The wizard components run behind the scenes during Setup, but you can also run the Removal Wizard on its own.
Both the wizard and Office 2003 Setup use the same logic and the same text file (.opc file) to detect and remove unneeded or obsolete files and settings from users’ computers. You can determine which previous versions of Office applications are removed by setting options in a transform (.mst file). You can also customize the .opc file so that only the files and components that you specify are removed.
