Question details
The user is unable to complete the installation of the SharePoint Server KB5002816 update.
- Product
- SharePoint Server
- Device & OS
- not provided
- Scenario
- Applying the KB5002816 cumulative update to a SharePoint Server environment.
- Observed behavior
- The installation process halts near the end with an 'Update failed' error, and JavaScript-related entries are recorded in the installation logs.
Ensure you have full farm administrator privileges and verify that you have downloaded both the language-independent and the correct language-dependent update packages for your server architecture.
Install Combined Updates and Run Configuration Wizard
Resolves the issue by providing the missing language-dependent resources required for the KB5002816 update to complete successfully.
A complete SharePoint Server update requires installing both the language-independent and language-dependent fixes together. Failing to do so often results in JavaScript-related log errors and an aborted installation.
Download the applicable language-dependent update package, such as KB5002802, from the official Microsoft Update Catalog.
Run the executable for KB5002816 along with the language-dependent package (KB5002802) on every server in your SharePoint farm.
Launch the SharePoint Products Configuration Wizard from the Start menu on each farm server to finalize the update and upgrade the databases.
Verify SharePoint Workflow Manager Requirements
Addresses update failures caused by missing Workflow Manager prerequisites introduced in recent cumulative updates.

Frequently Asked Questions
Why does the SharePoint update fail with JavaScript-related log entries?
JavaScript-related errors in the update logs typically indicate that a required language-dependent update package was not installed. Installing the corresponding language-dependent package (like KB5002802) alongside the main update usually resolves these errors.
Do I need to run the SharePoint Products Configuration Wizard on every server?
Yes. After installing the update binaries, you must run the SharePoint Products Configuration Wizard on every server in the farm to correctly apply changes to the services and upgrade the configuration databases.
Why is the update checking for Workflow Manager if I don't use workflows?
Recent SharePoint cumulative updates include validation checks for modern workflow components. You may need to install the SharePoint Workflow Manager components to satisfy these prerequisite checks during the update process, regardless of your actual workflow usage.
