I had SQL Server 2008 Express installed in this computer and wanted to install R2 and then the problems begun. I tried almost everything, uninstall previous version, delete registry keys, reboot, download software again and still get the same error.
2011-12-14 09:32:37 Slp: Running Action: PreMsiTimingConfigAction
2011-12-14 09:32:37 Slp: The object state property 'workflow' is null/empty.
2011-12-14 09:32:37 Slp: Error: Action "PreMsiTimingConfigAction" failed during execution.
2011-12-14 09:32:37 Slp: Completed Action: PreMsiTimingConfigAction, returned False
I've also read all the messages about this error but still not working. Is there any solution other than re-install the OS again?
Thanks for your help.
