Recently I had four Windows updates fail to install during automatic update. After that I searched and found the individual download pages for each update so I tried that and they all failed to install that way also. All for of them returned the following error message: Required installation branch was not found in INF file. I have no idea myself what required installation branch the error message is referring to.
The four updates are KB954600,KB952287,KB55069, and KB946648. If anyone has any ideas on how to resolve both the installation branch and the failed updates problems I'd sure appreciate your input!
