Microsoft SQL Server 2008 Express can't install
Tried to install SQL Server 2008 Express but the installation said there was a problem and couldn't install the server. 

Now even though it said that it still added the configuration tool and all, but the SQL service isn't running. So everytime I try to create a database file in Visual C# 2010 Express it says I need a 2005 or 2008 SQL installed. 

In the list of services I have a service named MYSQL51 which can't be started because it issues an error saying it couldn't find the application responsible for running this service. That is probably because I uninstalled MySQL 5.1 from my machine before installing SQL Server 2008 Express. I also have wamp 2 installed which when turned on says that MySQL is running. 

The end situation is this: Can't create db files in VC# because it says I have no 2005 or 2008 SQL installed, if I try to install it doesn't create a working/running SQL service in Services' list, the only SQL related service in the list is MYSQL51 which is off and can't be started because MySQL 5.1 was deleted, and wamp's MySQL is working fine. What do?

PS I also tried to Add SQL 2008 Express as a feature through the Visual C# 2010 Express installation, but it failed and now the option is greyed out.
