256986 Description of the Microsoft Windows Registry



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: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

 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.</ol>

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.
