256986 Description of the Microsoft Windows registry



SYMPTOMS
When you try to install Microsoft SQL Server 2005 Service Pack 1 (SP1), later SQL Server 2005 service packs, or a SQL Server 2005 hotfix package, SQL Server 2005 Database Services or SQL Server 2005 Analysis Services may not be installed successfully. Additionally, the following error message may be logged in the Setup log file:

Error 29528. The setup has encountered an unexpected error while Setting Internal Properties. The error is: Fatal error during installation.



CAUSE
This issue occurs because of one of the following reasons:
 * An operation has removed the local groups for the initial installation of SQL Server 2005.
 * An operation has changed the security identifiers (SID) for the local groups.



WORKAROUND
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

For a stand-alone installation of SQL Server 2005
 Remove the following registry subkeys that store SID settings:  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL. \Setup\SQLGroup HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL. \Setup\AGTGroup HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL. \Setup\FTSGroup HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL. \Setup\ASGroup

Note In these registry subkeys, MSSQL. is a placeholder for the corresponding value on a specific system. You can determine MSSQL. on a specific system by examining the value of the MSSQLSERVER registry entry under the following registry subkey:

</li> Reinstall the SQL Server 2005 service pack or the SQL Server 2005 hotfix package.</li></ol>

For a clustered instance of SQL Server 2005

 * 1) Follow step 1 in the procedure for a stand-alone installation of SQL Server 2005.
 * 2) Reinstall the clustered instance of SQL Server 2005.
 * 3) Reinstall the SQL Server 2005 service pack or the SQL Server 2005 hotfix package.

STATUS

<div class="moreinformation_section">

MORE INFORMATION
The initial installation of SQL Server 2005 creates local groups and stores the SID settings for the local groups in the registry. However, the local groups or the SIDs may be removed or changed when you perform the following operations:
 * Install the Active Directory directory service on a member server.
 * Remove Active Directory from a domain controller.
