My apologies, I guess I should of communicated more clearly.
After one clicks on box to add Net Framework 3.5 in your computer settings, your computer will ask to download it from windows which one authorizes. Your computer will then search, download and install Net 3.5. Hopefully your computer installs it successfully.
In my case the install failed and I encountered a further error message. The "create windows media" link was the mechanism I utilized to address that error message I encountered during the attempted installation as it essentially repairs and reinstalls windows. After that repair so to speak, I was then able to return to settings/control panel, click on Net 3.5 with windows being able to successfully search, download and install it.
