Hi, Claude.
I am really happy to see the progress that has been made!
Please do the updates in the order provided by Richard. In addition, pay attention when an update indicates that a restart is needed and, although it will make the process longer, please shutdown/restart your computer when required before moving to the next. Also, even if not prompted for a restart, after completing all of the .NET Framework updates, restart your computer before moving on to KB237811.
