Is it possible to install Microsoft SQL Server 2012 on Windows Server 2008 R2 Datacenter?and what are sql server 2012 requirements to get installed?
On the Windows Server 2008 R2 Datacenter - I have .Net Framework 3.5.1 Features(.Net Framework 3.5.1) and I even manually installed .Net Framework 4.
The operating system on this computer does not meet the minimum requirements for SQL Server 2012. For Windows Vista or Windows Server 2008 operating systems, Service pack 2 or later is required. For windows 7 or windows server 2008 R2, Service pack 1 or later is required.
