No services listed when SQL Server Express 2008 R2 Installed on local computer

I cannot开发者_如何学Python get my local computer to run SQL Server. I looked in the SQL Server configuration manager and noticed that there are no SQL Server Services listed. That can't be right. I also noticed that There are two Managers listed in the SysWOW64 folder (I'm running Win7): SQLServerManager10.msc and SQLServerManager.msc. Neither show any services at all. When trying to connect via SSMSE, I get the standard:

    A network related or instance specific error occurred while establishing a 
connection to SQL server...

I haven't installed a prior version, but did try to uninstall and reinstall using the Web platform installer from Microsoft. Any suggestions?

Thanks

I had the same problem and as Brian said, I was missing SQL Server Express. So I download SQL Server 2008 R2 Express and I installed it. now everything works fine.

Note that I thought I already installed it when I installed SQL Management Studio R2. Now, be aware that when installing SQL Management Studio R2, you are not installing SQL Server and you won't get any SQL Server Services in your Sql Server Configuration Manager -> SQL Server Services. You also need to download and install SQL Server Express.

Is SQL Server listed in services? (Start->Run->Services.msc) If so, is it running?

That is an instance error, meaning you cannot connect to the instance. Most likely there is no instance installed on this machine. Meaning your not connecting correctly to the instance. Connect to the database engine again and check the server name and make sure your connecting to the correct server name or the local host, depending if this is a local machine or if this is on a server. Go back through setup and see if there are any features that didn't get installed. Try that and see if it works. If not then reinstall SQL Server and make sure all folders are removed and nothing is left behind before you reinstall.
