I was trying to install SQL server management studio 2008 on Windows Server 2003 SP2 x86 Standard edition and but I couldn't install it. I got an error saying install "Windows Installer 4.5" so I installed Installer 4.5 (WindowsServer2003-KB942288-v4-x86).

Even after that I wasn't able to install SQL server, I googled and found that I need to install PowerShell 1.0. (WindowsServer2003-KB926139-v2-x86-ENU). I also installed PowerShell MUI pack (WindowsServer2003-KB926141-x86-ENU) along with it.

Then the SQL server installation started, only to end with a MOF error "SQL server installed unsuccessfully" and asked me to uninstall the SQL server and reinstall it. Ever since I uninstalled the SQL server management studio 2008, my Server 2003 could not load windows explorer. I checked the event logs and found the following error.

I couldn't find any solution for this error on Google.

**Event Type: Error

Could somebody help me here?

Thanks Pandu
