Hello All,
I was experiencing the same issue with 2862330 and 2862335. I was finding the updates were installing but were not making the system files "rev up" to the expected versions even while getting succesful installations of the patches. Uninstall and manual installation of the MSU file was not working either.
I found the "owner" of the sys files that were to be updated was "trusted installer", and the "administrators" group only had read permissions on the files due to least privilege most probably. In any case, giving the "admin" group "full control" of the sys files in question did allow the update to go through succesfully and clear the scan afterwards.
Hope this helps, and thanks for all of YOUR posts and advice, they always help out...
