Alright so I was going to make a test server, just to practice with server things, and to learn how to run/create a server. I am using Microsoft SQL Server 2012. I can't even install the ****** sql server. I have had 2 people claiming they understand how to do it and have done it before, no luck. I tried 2008 SQL but kept getting some begininvoke error. I believe I do have a sql server installed, from many tries, but cant open via managment tool. Would really apreciate help

thank you
