I’ve installed SQL Server 2005 on Windows 7. My Windows 7 installation is 64 bit, but I couldn’t figure out how to get the 64 bit SQL Server so I have the 32 bit version. I installed all 4 service packs, and restarted my computer.
While SQL Server Management Studio is willing to launch, I do not have the mssqlserver service, or any other service that could be SQL Server.
How do I get the SQL Server service running so I can use SQL Server 2005 on my Windows 7 machine?
As you can see, I have no services available. I did not get any error messages when I did the install.

Well, I gave up, uninstalled everything, and re-installed it, this time just doing the basic install and then installing SP4. That worked.
I guess the moral of this story is just use teh last service pack available, rather than all of them one at a time.
