Microsoft System CLR Types for SQL Server 2012 WSUS Download: Official Integration Package

I learned the hard way that missing this package breaks SQL Server 2012 features. The official System CLR Types package enables hierarchyid, geometry, and geography types across client applications.

Microsoft hosts the x86 and x64 versions on their download center. It’s a small install that takes 2 minutes and requires admin rights. WSUS deployment is straightforward once you have the right .cab files.

Without it, spatial data queries and SQL Server Management Studio throw errors. The version must match your SQL Server 2012 release exactly—no newer, no older.

Works on Windows 7 through 10, Server 2008 R2 through 2019. Always download from Microsoft’s official site to avoid tampered files.

Step-by-Step Instructions for Integrating Microsoft System CLR Types for SQL Server 2012 via WSUS

Here’s the procedure I use to deploy this package across enterprise environments without errors.

Log in to the WSUS server and open the Update Services console. Navigate to Options and select Synchronize Now to ensure the latest updates, including the System CLR Types package, are available for deployment.

Verify the synchronization completes successfully—check the Last Synchronization Status in the console. If it fails, retry or check network connectivity to Microsoft’s update servers.

In the WSUS console, go to Updates and use the search bar to filter for “System CLR Types for SQL Server 2012”. The update should appear under the Critical Updates or Feature Packs category.

Right-click the update and select Approve. Choose the target group (e.g., All Computers or a specific OU) and confirm the approval. This makes the package available for client installation.

On the client machines, open Group Policy Editor (gpedit.msc) and navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Update.

Enable Configure Automatic Updates and set it to Download and install or Notify for download and install. Ensure the Specify intranet Microsoft update service location policy points to your WSUS server (e.g., http://your-wsus-server:8530).

On each target machine, open Command Prompt as Administrator and run wuauclt /detectnow. This forces the client to check the WSUS server for pending updates immediately rather than waiting for the next scheduled scan.

Alternatively, use PowerShell with the command Get-WindowsUpdate -Install if the PSWindowsUpdate module is installed. Monitor the Windows Update history to confirm the System CLR Types package appears and installs.

After installation, open Control Panel > Programs and Features and check for Microsoft System CLR Types for SQL Server 2012 in the list. Its presence confirms successful deployment.

For SQL Server validation, open SQL Server Management Studio and run a simple CLR integration test, such as creating an assembly. If no errors appear, the package is functioning as expected.

Tips and Common Mistakes

These insights will help you navigate the deployment process smoothly and avoid common pitfalls.

Synchronization Best Practice: In Step 1, always verify the Last Synchronization Status before proceeding. I learned this after a failed deployment when I assumed synchronization completed successfully. Network issues or server timeouts can cause silent failures, so double-checking saves hours of troubleshooting. Real talk: this is the most overlooked step in enterprise deployments.

Approval Targeting: When approving the update in Step 2, be precise with your target group selection. If you select All Computers for a test environment, you might accidentally deploy to production servers. I recommend creating specific OUs for testing and production to prevent this exact scenario—trust me on this.

Client-Side Configuration: For Step 3, ensure the Specify intranet Microsoft update service location policy uses the exact WSUS server URL, including the port number (e.g., http://your-wsus-server:8530). A single typo here will cause clients to ignore your WSUS server entirely and pull updates from Microsoft directly.

Verification Technique: In Step 5, don’t just check Programs and Features—run that CLR integration test in SQL Server Management Studio. I’ve seen cases where the package appeared installed but wasn’t functioning properly. The test assembly creation is your only true confirmation of success.
