Fix SharePoint 2013 Subsite Creation Error: GetTypes Assembly Failure
Question details
The user is experiencing a 'GetTypes Assembly Failure' error when attempting to create a subsite in SharePoint 2013.
- Product
- Microsoft SharePoint 2013 Server
- Device & OS
- not provided
- Scenario
- Creating a new subsite within a SharePoint 2013 Server environment.
- Observed behavior
- Subsite creation fails because an Analysis Services add-in assembly or one of its dependencies cannot be loaded.
Ensure you have farm administrator access to your SharePoint 2013 Server and access to the SharePoint ULS (Unified Logging Service) logs to capture the complete error stack trace.
Consult the Microsoft Q&A Community for SharePoint Server
Because this is a SharePoint 2013 Server-specific issue rather than SharePoint Online, the most effective resolution path is engaging with Microsoft's dedicated server management community.
SharePoint Server issues often require deep diagnostic review of farm configurations, customized web parts, and locally installed dependencies that differ vastly from standard cloud environments.
Open your web browser and go to the official Microsoft Q&A platform for enterprise products.
When creating a new post, select the 'SharePoint Server' and 'SharePoint Server Management' tags to ensure your question reaches the right experts.
Include the complete assembly error message from your server logs, the correlation ID, and details of any recently installed or updated add-ins (such as SQL Server Analysis Services).
Review ULS Logs and Add-in Dependencies
Perform initial administrative checks to identify which specific Analysis Services assembly is failing to load during subsite creation.
Boost Your Team's Productivity with WPS Office
While managing complex SharePoint server deployments and dependencies can be challenging, creating and sharing daily documents shouldn't be. WPS Office provides a lightweight, highly compatible alternative to Microsoft Office that meets your team's documentation needs without the enterprise overhead.
Frequently Asked Questions
Why does the GetTypes assembly failure only happen when creating subsites?
This error typically occurs during subsite creation because SharePoint attempts to activate site features or templates that rely on specific third-party assemblies or SQL Server Analysis Services add-ins that are missing or improperly configured on the server farm.
Is SharePoint 2013 still supported by Microsoft?
SharePoint Server 2013 reached its end of extended support in April 2023. Microsoft no longer provides technical support or security updates, making it highly recommended to upgrade to a newer version of SharePoint Server or migrate to SharePoint Online.
Where can I find the correlation ID for the SharePoint error?
The correlation ID is a unique GUID usually displayed prominently at the bottom of the error page when a failure occurs in SharePoint. Server administrators use this ID to quickly locate the exact stack trace and assembly failure details in the server's ULS logs.
