Update Installers can sometimes be problematic and often it is hard to deduce the root cause of a fix pack installation failing. The obvious reason for failure is often the amount of disk space left on the filesystem, folder permissions and environment variables, namely system paths.

When using the silent option of installing a fix pack, the installer may not accurately report the root cause of a failed installation in the logs.
You can opt to try a graphical installation. Using the manual install approach can often shed light on errors that are reported in the GUI, but not in the silent installer.
