Kaspersky Update Failure: Required File Missing from Local Source

[ymc]

I have downloaded the required resources using Kaspersky Update Utility and transferred them to the internal management server via FTP. In the task settings, I configured the update to be performed from a local folder. However, an error occurred stating "A file necessary for the database update is missing from the update source." I couldn't find relevant logs to identify which files are missing.
