Windows 98 crashing required re-installing Office 2000 Premium. CD1 was re-loaded but CD2 with Publisher and Shared Clip Art refuses to istall. Uninstalling Publisher is not possible since it does not feature in the Add/Remove list of the reinstalled Win98. The error message reads: "This patch could not be opened. Contact the application vendor to verify that this is a valid Windows installer package". The installer is the most recent version. Would someone know of the critical files which hinder setup.exe.
