I have performed Denodo Solution Manager silent update installation and I encountered the same error. When I checked, the logging capabilities of the updates installer are working correctly and there is no impact on Denodo updates installation process. I believe this is not an error but only a partial warning message and can be ignored.
If you are a user with support access and still consider that it is an error in the Denodo Platform, I would suggest you raise a support case in the [Denodo Support Site](https://support.denodo.com/).
Hope this helps!
