I'm getting the notice 'Please install KB2999226 on your machine before initiating installation' when trying to install Update 5.
What is KB2999226?
Update for Windows 7 for x64-based Systems (KB2999226)

Thanks for your clarification! Microsoft makes it too easy for someone to download the wrong version — the same KB applies to both 32-bit and 64-bit versions, and as I discovered you may end up with the 32-bit version.

Take a look at this wiki:
