I don't know what this thing does and I'm having trouble, caring to know but everytime I turn off my computer it takes over trying to unsuccessfully install itself. I've been away all week and come home to it still installing. Its like Hal from Space Odessy 2000. I'm running 32-bit Win 7. Trend Micro Titanium AV. You are the fisrt resource I've tried.

SQL Server is a relational database engine. Some app you installed may be using as a backend data store. I'd ask them here. http://answers.microsoft.com/en-us/windows/forum/windows_7?page=1&tab=all Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

I've installed SQL Server 2005 Express on Windows 7, and I don't believe it will try repeatedly if it fails to install. I think some other application is trying to install it, as suggested. Possibly it cannot install because the setup program was not run using the "Run as administrator" feature (right clicking the setup program and selecting "Run as administrator). I know some virus software uses SQL Server. If you have installed something recently, perhaps you can uninstall it. Then run the setup again by right clicking the setup program and selecting "Run as administrator". Richard Mueller - MVP Directory Services
