XADM: Exchange Server Setup Halts Copying MAPI32.DLL

 Last reviewed: February 12, 1998
Article ID: Q148272

The information in this article applies to:
  • Microsoft Exchange Server, versions 4.0 and 5.0

SYMPTOMS

The Microsoft Exchange Server Setup program may pause with a dialog box stating the following: 

   STOP  Setup cannot copy <cd>:\SETUP\<platform>\MAPI32.DLL:
   The file cannot be overwritten because it is in use by another process.

CAUSE

The Microsoft Exchange Server Setup program tries to install MAPI32.DLL to the <winnt>\SYSTEM32 directory during installation. It is possible that some mail-aware application or Microsoft Windows NT service is running that has already loaded this DLL file; therefore, the file is in use and cannot be overwritten.

RESOLUTION

Close all running applications except for the Setup program. Stop all services that are mail-aware (capable of sending e-mail). Click the Retry button.

If this does not allow the Setup program to continue, or if the application or service cannot be determined at this time, select Ignore. The Setup program should complete.

At this point, the application or service using MAPI32.DLL must be determined and temporarily halted so that <cd>\SETUP\<platform>\MAPI32.DLL can be manually copied to the <winnt>\SYSTEM32 directory.

You need to be aware of some less obvious MAPI-aware applications, specifically, some uninterruptible power supplies, include monitoring software that runs as a Windows NT service. This software may be mail-aware and configured to send e-mail to a system administrator under specific monitored conditions.

STATUS

In Microsoft Exchange Server version 4.0, this behavior is by design and will not be changed.

Microsoft has confirmed this to be an issue in Microsoft Exchange Server version 5.0. This has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0.
