SQL Server 2008 Installation Failure, Or You Are A Stupid MOF!

May 27, 2010

I ran across an installation issue with SQL Server 2008 on a Windows Server 2008 server the other day that baffled me a little bit.  I was installing an additional instance of SQL Server 2008 on a server that already had a SQL Server 2008 instance and right before the installation completed, it died with the error:  “A MOF Syntax error occurred.”  Further investigation into the Setup Bootstrap logs gave this detail:

An error occurred while processing item 1 defined on lines 14 – 16 in file D:\Program Files\Microsoft SQL Server\MSSQL10.TMS_MODELING\MSSQL\Binn\etwcls.mof.transformed:

2010-05-18 13:41:02 Slp: Configuration action failed for feature SQL_Engine_Core_Inst during timing ConfigNonRC and scenario ConfigNonRC.

 

Much investigation on the internet turned up a lot of people that have been having this issue, but very few answers.  After many installs and uninstalls, I finally tried the following, which seemed to work:

 

  • I ran the setup.exe as an administrator (right click on setup.exe and click “Run as administrator) even though I am a local administrator on the box.
  • I installed SQL Server using the Network Service account instead of the normal domain service account.
  • The installation succeeded and I just went into Configuration Manager and changed the service account to the domain account after the installation.
