Comments from another user
"Had same error code.
Also tried changing various access rights.
All without success.
Even downloaded the update files individually. But that would give an error on
attempting to copy the file branches.inf.
This lead to the solution.
For whatever reason, the file branches.inf
located in C:\windows\inf was made ReadOnly.
Cleared this ReadOnly flag and the installation of the updates worked smoothly."
