FineBuild can install and configure .Net 4.0 as part of the SQL Server install process.

You must Install .Net 3.5 for all editions of SQL Server prior to SQL2017, but SQL Server 2012 and above requires that .Net 4.0 is installed prior to starting the main SQL Server install. It is recommended that .Net 4.0 is installed for all SQL Server installs, to minimise risks if .Net 4.0 is installed at a later date.

For some editions of SQL Server or versions of Windows the install media for .Net 4.0 must be downloaded, for others the install media is included. The table below shows when you must do a download.

Operating system	SQL Server Version	Express Edition	Other Editions
Windows 2012 or above	any	Included	Included
Windows 2008 R2 or below	SQL2012	Download	Included
	SQL2008 R2	Download	Download
	SQL 2008	Download	Download
	SQL 2005	Download	Download

Download for Windows 2012 or above

This covers Windows 2012, Windows 2012 R2, Windows 8 and Windows 8.1.

If you are installing on Windows 2012 or above, then .Net 4.0 is built in to this version of Windows. No download or install is needed.

Download for Windows 2008 R2 or below

This covers Windows XP, Windows 2003, Windows Vista, Windows 2008, Windows 7 and Windows 2008 R2
