The information in this article applies to:

  • Microsoft Exchange Server 5.5
This article was previously published under Q248487

SYMPTOMS

When you install Service Pack 1 (SP1) for Microsoft Exchange Server 5.5, the installation may stop and you may receive the following error message:
Microsoft Exchange Server Setup: store.exe - Entry Point Not Found
The procedure entry point hz_ascii @24 could not be located in the dynamic link library GAPI32.dll.
The following error message also may appear:
The service did not respond to the start or control request in a timely fashion.

Microsoft Windows NT
ID no: 0xc002041d

CAUSE

This behavior occurs when the existing version of Gapi32.dll differs from the version that the Update.exe or Setup.exe program expects.

RESOLUTION

To resolve this issue, stop all services related to Exchange Server and then reinstall the service pack. Follow these steps:

  1. Stop all Exchange services, including Microsoft Internet Information Server services if Outlook Web Access is installed.
  2. Move the Gapi32.dll file from SP1 to the Exchsrvr\Bin folder.
  3. Reinstall Microsoft Exchange Server 5.5 SP1.
