There can be various ways in which you can check if a particular application is installed or not. Easiest would be, you can check in 'Control Panel -> Add/Remove programs' - if program is installed, you should be able to uninstall from there.

In case, you want to check it via code, look here - example VB.NET[^]

The question is not quite clear but you can check for example from Windows Services using Control Panel if SQL Server service exists.

If you want to do this programmatically, you can use for example SqlDataSourceEnumerator[^] to list all existing instances.

And possibly (depending on your needs) you can simply try to connect to an instance using SqlConnection[^]

If you're actually trying to deploy SQL Server Express with your application, have a look at http://msdn.microsoft.com/en-us/library/bb264562(v=sql.90).aspx[^]

Solution 3

If you want to check that if SQL server is available then use SqlDataSourceEnumerator[^] as Mika said and if you want to see if they are express version or not try to run this query on them :

SQL

select @@VERSION

If there was and Express Edition in output string then it should be an express edition.

But also consider using an install program for your program from third parties because they handle all prerequisites for your program and you will not worry for this issues any more.
