~/Troubleshooting SQL Server 2008 R2 install on Windows Server 2003 with Windows Platform Installer – WMI service

28 Feb 2013

Short story. Trying to install SQL Server 2008 R2 Express on a Windows Server 2003 (SP2) machine using WebPI – usually the best way to get server bits by far – but it fails with a meaningless message after a lengthy reboot that interrupted a small office.

I tried the standalone installer and got a more helpful error regarding the Windows Management Instrumentation (WMI) service. In Services the WMI service appeared to be running fine but this MSDN thread reveals the problem and gives a solution. It’s an old problem that I’ve seen before relating to corrupt WMI bits. The forum post provides the following batch file that reregisters the service:

@echo on
cd /d c:\temp
if not exist %windir%\system32\wbem goto TryInstall
cd /d %windir%\system32\wbem
net stop winmgmt
winmgmt /kill
if exist Rep_bak rd Rep_bak /s /q
rename Repository Rep_bak
for %%i in (*.dll) do RegSvr32 -s %%i
for %%i in (*.exe) do call :FixSrv %%i
for %%i in (*.mof,*.mfl) do Mofcomp %%i
net start winmgmt
goto End

if /I (%1) == (wbemcntl.exe) goto SkipSrv
if /I (%1) == (wbemtest.exe) goto SkipSrv
if /I (%1) == (mofcomp.exe) goto SkipSrv
%1 /RegServer

goto End

if not exist wmicore.exe goto End
wmicore /s
net start winmgmt
