IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SYMPTOMS

When attempting to install Exchange Server 5.5, or running Update.exe for Exchange 5.5 Service Pack 1, you may receive the error message:

Missing entry points in Gapi32.dll

CAUSE

This occurs when there is a mismatch between an existing version of Gapi32.dll and the version that Update.exe or Setup.exe is expecting.

WORKAROUND

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

Start Registry Editor (Regedt32.exe).

Locate the following key in the registry:
```
      HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session
      Manager\KnownDLLs 
```
NOTE: The above registry key is one path; it has been wrapped for readability.

On the Edit menu, click Add Value, and then add the following registry value:


      Value Name: Gapi32
      Data Type:  REG_SZ
      Value:      Gapi32.dll

Quit Registry Editor.

You must restart your computer for this change to take effect.

MORE INFORMATION

The error mentioned in the "Symptoms" portion of this article can be noted during an upgrade to Exchange Server version 5.5 or a new installation to Exchange Server version 5.5, as well as during the service pack update.

Placing the missing entry in the registry allows the software program to proceed normally.
