This article addresses a specific issue encountered when deploying Microsoft updates through GFI LanGuard, where the process fails with Error 13: The Data is Invalid. This error may also appear as ERROR_INVALID_DATA in the Windows Operating System. The error indicates a problem with the update file itself rather than an issue with the GFI LanGuard software. Understanding the nature of this error is crucial for system, network, and database administrators managing software updates in a business environment.
The solution to this problem involves a two-step approach.
Firstly, it is recommended to reach out to Microsoft Support for assistance, as the error is rooted in a Microsoft issue. Their team can provide specific guidance on resolving this error.
Secondly, to validate that the error is not related to GFI LanGuard, download the problematic patch directly from the Microsoft Update Catalog. Attempt to manually install the update by double-clicking the downloaded .msu file on the target system. If Windows displays the same error during this manual installation, it confirms that the issue is with the Microsoft update file itself and not with the GFI LanGuard deployment process. This validation step is critical for isolating the problem and ensuring that the correct support channel is pursued for resolution.
