What order of installation I must follow and which versions for visual studio, SQL server and SSMS?

18 Sep 2017 by OriginalGriff

I always install SQL server first, then Visual studio - the reason is that VS uses SQL, so if it's already installed, it doesn't add it's own version. I've had problems with VS before after installing SQL "over the top" of it. SSMS installs as part of SQL Server, so that shouldn't be a problem.
