Recently I’ve needed to apply 2 patches to our Windows 2008 R2. But both patches show me error “The update is not applicable to your computer”. But I knew for sure, that these updates were applicable, because installed file’s version was lower than the one contained in hotfixes.
In Setup log I’ve got “Windows update could not be installed because of error 2149842967” error.
The problem was that someone disabled Windows Modules Installer service on this machine, which is TrustedInstaller.exe process. After enabling and running this service, I’ve installed both patches successfully.
