The file, Nxpext32.dll is missing from your computer, or you removed Netscape Navigator but did not remove the reference to it in the Outlook Add-in Manager.

Missing cc:Mail files.
You should obtain and install the most recent 32-bit VIM libraries from Lotus. These file are available for download at the Lotus Support Web site. In addition, the Export.exe, Import.exe, and Ie.ri files should be copied to the System folder, if you are using Microsoft Windows 95 or 98, or to the System32 folder, if you are using Microsoft Windows NT 4.0. These files are normally stored in the Ccadmin folder on the cc:Mail post office server.
