Step 1: Enable
Microsoft .Net Framework 3.5 SP1 and
Download and install
Microsoft .Net Framework 4.0.
- Note: LocalDB does not require any .NET Framework installation.
- Note: SQL Server Express (with database engine only) can work with either .NET 3.5 SP1 or .NET 4, there is no need to have both enabled.
Step 2: Download Microsoft® SQL Server® 2012 Express.
Note: Microsoft® SQL Server® 2012 Express includes both 32-bit and 64-bit versions. SQLEXPR32_x86 is a smaller package that can be used to install SQL Server Express onto only 32-bit operating systems. SQLEXPR_x86 is the same product but supports installation onto both 32-bit and 64-bit (WoW) operating systems. SQLEXPR_x64 is a native 64-bit SQL Server express and supports installation onto only 64-bit operating systems. There is no other difference between these packages. Microsoft® SQL Server® 2012 Express is not supported on IA64 systems.
