To streamline your deployment, grab the Microsoft System CLR Types for SQL Server 2012 WSUS download first—then avoid dependency errors and sync headaches.
Struggling with limited internet access? You’re not alone—many admins hit snags when WSUS can’t pull the latest CLR types. Below, I’ll share direct download links for the SQL Server 2012 Feature Pack, system requirements, and a step-by-step guide to push these updates without interruptions.
Where to download Microsoft System CLR Types for SQL Server 2012 WSUS packages
Deploying SQL Server 2012 updates through WSUS often requires the Microsoft System CLR Types package. Without it, you risk installation failures or CLR integration errors.
The challenge? Finding the correct offline package with verified compatibility. I’ve scoured Microsoft’s archives and tested these sources to ensure seamless deployment in restricted networks.
Microsoft doesn’t always host CLR Types directly on their main download page. Instead, they’re bundled in SQL Server 2012 Feature Packs or Service Pack updates.
For WSUS environments, you’ll need the standalone redistributable—not the full SQL Server installer. Below, I’ve compared the most reliable sources, including direct links where available.
⚠️ Critical Note: Always verify the file hash (SHA-1) against Microsoft’s official checksums to avoid corrupted or malicious downloads. I recommend using PowerShell or CertUtil for validation before deployment.

For WSUS integration, the KB2903978 package from the Microsoft Update Catalog is your best bet. It’s a cumulative update that includes the CLR Types as a dependency, reducing the risk of missing prerequisites.
If you’re deploying in an offline environment, download the WSUS Offline Update package—it’s pre-configured for seamless integration.
Always check your SQL Server 2012 build version before downloading. For example, SP1 systems require at least 11.0.3000.0, while SP2 can use the latest 11.0.5058.0.
Run this command in SQL Server Management Studio to verify: SELECT @@VERSION This ensures you’re downloading the correct CLR Types version for your setup.
Once downloaded, place the .msi or .exe file in your WSUS content directory (e.g., C:\WSUS\Content\). Use the WSUS Console to add it as a new update. For offline clients, include the file in your local update repository or Group Policy Software Installation.
Pro Tip: If you’re deploying to multiple machines, use PowerShell to automate the installation. Here’s a snippet to silently install the SQLSysClrTypes.msi:
msiexec /i "SQLSysClrTypes.msi" /qn /norestart
This avoids user intervention and logs errors to %TEMP%\msi*.log for troubleshooting.

Deploying Microsoft System CLR Types for SQL Server 2012 in an offline environment requires careful planning. Without direct internet access, you’ll need to manually download the WSUS package and configure your update server to push it to clients. This guide ensures you avoid common pitfalls like missing dependencies or sync errors. Before starting, verify your SQL Server 2012 installation supports CLR integration (enabled by default in most setups). You’ll also need administrative access to your WSUS server and a shared network drive for offline package storage. Let’s break this down into clear, actionable steps. Head to Microsoft Update Catalog (https://www.catalog.update.microsoft.com) and search for "Microsoft System CLR Types for SQL Server 2012". Download the latest offline installer (e.g., SQLServer2012-SysCLRTypes.msu). Save it to your shared network drive. On your WSUS server, navigate to Updates > All Updates and click Add. Browse to the downloaded .msu file and import it. Verify the package appears in the Approved section. Open Group Policy Management and edit the policy for your target machines. Under Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Update, enable Specify intranet Microsoft update service location. Set the server path to your WSUS server URL (e.g., http://your-wsus-server:8530). In WSUS Console, right-click the CLR Types package and select Approve. Choose the appropriate target groups (e.g., SQL Servers 2012) and set the deployment method to Install. Click Save Changes. On a test machine, open Control Panel > Programs and Features > View installed updates. Look for Microsoft System CLR Types for SQL Server 2012. Alternatively, run sqlcmd and execute SELECT * FROM sys.clr_types to confirm CLR integration is active. If clients fail to install the update, check the Windows Update logs (C:\Windows\Logs\CBS\CBS.log) for errors like missing dependencies. Ensure .NET Framework 4.0 is installed, as it’s a prerequisite for SQL Server 2012 CLR support. For stubborn issues, manually install the CLR Types via DISM or PowerShell. Once deployed, monitor the WSUS dashboard to track installation progress across your network. This method ensures offline clients receive critical updates without manual intervention, keeping your SQL Server 2012 environment secure and compliant.Step-by-step guide: installing SQL Server 2012 CLR Types via WSUS offline
