XCLN: ErrMsg: Mapi32.dll Is Missing or Corrupted

ID: Q198289

The information in this article applies to:

Microsoft Outlook 98 Deployment Kit

SYMPTOMS

While you install Outlook 98 using the Outlook Deployment Kit (ODK), the installation appears to complete successfully. However, when you attempt to start the client, you receive the following error message:

MAPI32.DLL is missing or corrupted

CAUSE

Because Mapi32.dll is already in use by another application, the updated version of this file could not be copied over the previous version installed by Outlook 97. As a result, several other .dll files required by Outlook 98 are not installed either. Because the file is in use at the time of installation, it is considered locked open by the Setup program, and cannot be overwritten with the newer version of these files.

RESOLUTION

Close any programs that may be using Mapi32.dll, like Outlook or the Exchange client, before running Setup from the Outlook Deployment Kit either manually or through a login script.
