I need help installing SQL Server 2005 Enterprise edition.I really need to remove the current SQL Server 2005.installation that is no longer on my Add/Remove software list but yet still installed on the machine.

I tried to uninstall SQL Server Express / Developer Edition but it only removed it from my Add/Remove software list. It returned immediately but did NOT actually remove the product. (I'm now in a bad state.)

i tried to install SQL Server 2005 Enterprise and its says I'm blocked as all components are already installed - but they are not.

How can I remove all instance of previous one and install clean Enterprise edition on my server Thanks


First thing, try the manual un-installation instructions, found here.

If that doesn't work, you could try the Windows Installer Cleanup tool, found here. It says its only for Office products, but I've had good luck with many other things.
