To deploy the Microsoft System CLR Types for SQL Server 2012 WSUS download offline, you’ll need the precise installer for your legacy setup.
If you're stuck chasing dead Microsoft links or dealing with WSUS rejection errors, this guide cuts through the noise with direct download sources and step-by-step deployment fixes. No more guessing whether your package is compatible.
Where to download Microsoft System CLR Types for SQL Server 2012 WSUS offline installer
Microsoft System CLR Types are essential for SQL Server 2012 environments to enable Common Language Runtime (CLR) integration. When deploying via Windows Server Update Services (WSUS), you need reliable offline installer sources to avoid dependency issues.
Microsoft no longer hosts direct downloads, but verified archives and third-party repositories provide trusted alternatives.
Always verify the file hash and version number (11.0.2100.60 for SQL Server 2012 SP1) before deployment. Using incorrect versions can break CLR functionality in stored procedures or triggers. Below, I’ve compiled the most reliable sources for offline installation, including Microsoft’s official archives and community-verified repositories.
| Source | Download Link | File Name | Version | Notes |
|---|---|---|---|---|
| Microsoft Update Catalog | https://www.catalog.update.microsoft.com | SystemCLRTypes.msi | 11.0.2100.60 | Search for "SQL Server 2012 SP1 CLR Types" |
| Microsoft Download Center (Archive) | https://www.microsoft.com/en-us/download/details.aspx?id=42295 | SQLServer2012SP1-FeaturesSetupx64.exe | 11.0.3000.0 | Extract via command line: /ACTION=Extract |
| GitHub (Community Archive) | https://github.com/microsoft/sql-server-samples/tree/master/samples/features/clr | SystemCLRTypes11.0.2100.60.msi | 11.0.2100.60 | Verified by SQL Server community |
| WSUS Offline Update (Third-Party) | https://www.wsusoffline.net | SystemCLRTypes.msu | 11.0.2100.60 | Pre-packaged for WSUS deployment |
For WSUS-specific deployments, I recommend using the WSUS Offline Update repository, as it packages the installer in .msu format—ideal for offline updates. Always cross-check the SHA-256 hash of the downloaded file against Microsoft’s official hashes to prevent tampering or corruption.
If you’re deploying to multiple systems, extract the SystemCLRTypes.msi from the SQL Server 2012 SP1 installation media using this command:
SQLServer2012SP1-FeaturesSetupx64.exe /ACTION=Extract /INSTALLSHAREDPRODUCTKEYS=1 /FEATURES=SharedTools /TARGETDIR="C:\SQL2012Extract"
This ensures you have the correct CLR Types for your environment.
Verify compatibility by checking the SQL Server 2012 version in SQL Server Management Studio (SSMS) under Help > About. Mismatched versions can cause CLR integration failures or permission errors during deployment.
Third-party repositories like GitHub or WSUS Offline Update are excellent for legacy systems, but always validate the digital signature using SignTool.exe to ensure authenticity. For example:
SignTool.exe verify /pa SystemCLRTypes.msi
This step is critical for enterprise environments where security compliance is a priority.
Once downloaded, store the installer in a secure, version-controlled repository to avoid redeployment issues. Label files with build numbers (e.g., CLRTypes_SQL2012_SP1_11.0.2100.60) for easy tracking in your WSUS catalog.
Pro tip: Use PowerShell to automate WSUS deployment. Here’s a snippet to add the update to your WSUS server:
Add-WsusUpdate -UpdateFilePath "C:\Updates\SystemCLRTypes.msu" -UpdateClassification "Updates"
This ensures seamless integration with your existing update workflows.

Step-by-step guide: deploying System CLR Types via WSUS for offline SQL Server 2012 systems
Deploying Microsoft System CLR Types via WSUS for offline SQL Server 2012 systems requires careful preparation to avoid common pitfalls. This process ensures your legacy systems receive critical updates without direct internet access, maintaining CLR integration and SQL Server compatibility.
Below, I’ll walk you through each phase, from offline installer prep to WSUS configuration and validation.
Before starting, ensure you have the SQL Server 2012 SP4 offline installer and the System CLR Types package (version 11.0.5058.0). Verify your WSUS server is running Windows Server 2012 R2 or later, as older versions may lack support for legacy SQL components.
Gather admin credentials for both the WSUS server and target SQL Server machines.
⚠️ CRITICAL STEP-LIST BELOW ⚠️
Download the System CLR Types package from Microsoft’s Update Catalog (use KB3173244 for SQL Server 2012 SP3/SP4). Extract the .msu file to a shared network folder accessible by your WSUS server.
Open the WSUS Console and navigate to Updates > Add Updates. Manually import the System CLR Types .msu file. Right-click the update and select Properties to set Deployment Targets to your SQL Server 2012 group.
In the WSUS Console, approve the System CLR Types update for the SQL Server 2012 target group. Select Available as the deployment method and ensure Deadline is set to a future date (e.g., 7 days from approval).
Use the WSUS Offline Update Tool (from Microsoft) to generate a custom update package. Include the System CLR Types update and any dependent Windows Updates (e.g., KB3058587). Save the package to a USB drive or network share.
On each SQL Server 2012 machine, run the WSUS Offline Update Tool from the shared location. Select the custom package and follow the prompts. Reboot the system if prompted.
Open SQL Server Management Studio and run SELECT SERVERPROPERTY('ProductVersion') to confirm the CLR Types are installed. Check the Windows Update History for the System CLR Types entry (KB3173244).
If installation fails, verify the .msu file isn’t corrupted (use sha256sum against Microsoft’s checksum). Ensure the SQL Server service account has local admin rights. For dependency errors, manually install missing updates via the WSUS package.
After deployment, monitor your SQL Server 2012 environments for CLR-related errors in the SQL Server Error Log. If you encounter permission issues, run the WSUS Offline Update Tool with elevated privileges. For large deployments, automate the process using PowerShell scripts to push updates silently.
Pro tip: Document the WSUS update approval timeline and deployment logs for auditing. This ensures compliance and simplifies troubleshooting if issues arise later. With these steps, your offline SQL Server 2012 systems will stay updated and compatible with CLR-dependent applications.
