When Identity Finder is launched or a search is initiated, an attempt is made to load specific Windows components (e.g., MAPI32.dll) that allow the searching of e-mail messages and attachments. If these Windows components become outdated, corrupted, or are replaced by another application, an error may be displayed and Identity Finder will be unable to continue.
The file MAPI32.dll is a Windows operating system file and is included on every Windows system. This file is used by e-mail applications and is required for Identity Finder to function as it contains the Windows messaging interface that allows Identity Finder to search, for example, Outlook and Outlook Express messages and attachments.
When the message, "The ordinal 140 could not be located in the dynamic link library MAPI32.dll" is displayed, the usual cause is a configuration issue with Eudora. If Eudora is not installed on the system, even if it is not in use, refer to the article Unable to find MAPI32.dll.
If Eudora is installed on the system, even if it is not in use, it may have replaced the Windows version of MAPI32.dll with a version incompatible with Identity Finder. Open Eudora and determine if it is set to use its MAPI server, "Always". If so, switch the value to "Only When Eudora Is Running" and then reboot the computer. After restart, launch Identity Finder to confirm that the issue has been resolved.
