Microsoft released a security update, “KB5002653,” for Excel 2016 in November 2024. However, users have reported issues with loading add-ins after applying this update. This article explains the problem in detail and provides recommended workarounds to help you manage this issue effectively.
Add-In Loading Issue After Applying KB5002653
Issue Overview
After installing the “KB5002653” update, some Excel 2016 users have encountered problems where add-ins (particularly .xla and .xlam files) fail to load correctly. The update causes a path truncation issue, where the first character of the add-in path is removed, leading Excel to be unable to locate the add-in file.
Microsoft’s Response
Microsoft has acknowledged this issue and has listed it on their official support page as a known problem. They recommend manually opening the add-ins as a temporary solution.
Detailed Explanation of the Issue
Failure to Load Add-Ins Automatically
Following the installation of “KB5002653,” Excel 2016 users may find that add-ins no longer load automatically and must be opened manually each time.
Path Processing Bug
The issue stems from a bug in Excel’s path handling, which removes the first character from the add-in path, preventing the add-in from loading. This bug disrupts the automatic loading process for add-ins, causing users to take additional steps to access them.
Recommended Solutions
Manual Add-In Loading
As a temporary workaround, follow these steps to manually load your add-ins:
- Open Excel.
- From the [File] menu, select [Open].
- Navigate to the add-in file (.xla or .xlam), select it, and open it.
Uninstalling the Update
If manual loading does not resolve the issue, consider uninstalling “KB5002653.” However, as this update includes important security fixes, use this option with caution. To uninstall:
- Open the [Control Panel].
- Go to [Programs and Features].
- On the left, click [View installed updates].
- Locate “KB5002653,” right-click, and select [Uninstall].

The “KB5002653” security update for Excel 2016 has introduced a known issue with loading add-ins. Microsoft recommends manually opening add-ins as a temporary solution while they investigate a permanent fix. Stay tuned for official updates from Microsoft to address this issue.
