SYMPTOMS
The Microsoft Exchange Server Setup program may pause with a dialog box stating the following:
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) such as anti-virus software, Compaq Insights Agents, Simple Network Management Protocol (SNMP), and so on. Click Retry.
If this does not allow the Setup program to continue, or if the application or service cannot be determined at this time, click Ignore. The Setup program should finish.
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.
