Check if SQL Server is installed on a machine through C#

Question

I am making an application which is a user interface to access 2 types of databases - SQLite and SQL Server.

The thing is, SQLite doesnt need to be \"installed\

Answer 1

If your app is installed on the machine in question, you could inspect the registry using something similar to this:

using Microsoft.Win32; 
RegistryKey RK = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\MICROSOFT\Microsoft SQL Server");
    if(RK != null)
    {
       // It's there 
    }
    else
    {
       // It's not there 
    }
