Installing Sql Server 2012 Express is a straightforward process, whether you are setting it up for the first time or adding features to an existing installation. This guide provides clear, step-by-step instructions for both scenarios, ensuring a smooth setup.
Installation for New SQL Server 2012 Express Users
If you are new to SQL Server 2012 Express, follow these steps to get it installed on your system:
Step 1: Enable or Install Microsoft .NET Framework
SQL Server 2012 Express requires the Microsoft .NET Framework to function correctly. You will need to enable Microsoft .Net Framework 3.5 SP1 or install Microsoft .Net Framework 4.0.
Note: SQL Server Express (with just the database engine) is compatible with either .NET 3.5 SP1 or .NET 4. Having both is unnecessary; choose one based on your system requirements or existing installations.
Step 2: Download and Run the SQL Server 2012 Express Installer
Download Microsoft SQL Server 2012 SP4 Express by selecting the appropriate download link for your system architecture (32-bit or 64-bit). Once downloaded, run the installer. The setup wizard will guide you through the remaining installation steps. Simply follow the on-screen prompts to complete the installation.
Adding Features to an Existing SQL Server 2012 Express Installation
For users who already have a basic installation of SQL Server 2012 Express and wish to add the complete SQL Server Management Studio feature, these steps will guide you through the process:
Step 1: Download the SQL Server 2012 Express SP4 Update File
Download the necessary Microsoft SQL Server 2012 Express SP4 file. This file will update your current SQL Server 2012 Express installation, allowing you to add new features.
Step 2: Run the Update File and Select Feature Addition
Execute the downloaded file. In the setup wizard, proceed to the “Installation Type” page. Here, choose the option “Add features to an existing instance of SQL Server.” Select the specific instance you intend to update from the available options.
Step 3: Choose Management Tools – Complete Feature
On the “Feature Selection” page, locate and select the checkbox next to “Management Tools – Complete.” This will add the full SQL Server Management Studio suite to your existing installation. Continue through the wizard to finalize the feature installation.
Understanding SQL Server 2012 Express Package Variations
Microsoft SQL Server 2012 SP4 Express is provided in different packages to accommodate various system architectures:
- SQLEXPR32_x86: A smaller package designed exclusively for installing SQL Server 2012 Express SP4 on 32-bit operating systems.
- SQLEXPR_x86: This package is compatible with both 32-bit and 64-bit (WoW – Windows on Windows) operating systems. It’s the same product as the 32-bit specific package but offers broader compatibility.
- SQLEXPR_x64: This is the native 64-bit SQL Server 2012 Express SP4 package, designed for installation only on 64-bit operating systems.
Functionally, there are no differences between these packages other than their compatibility with operating system architectures. Choose the package that aligns with your system’s architecture.
By following these steps, you can successfully install or update your SQL Server 2012 Express instance, ensuring you have the necessary tools and database engine for your development or application needs.
