    First error encountered: 0x80070643 - Which .NET Framework version is the Installer looking for?

    Second error encountered while update Windows 10 Insider Preview build 17733.1000 (rs5_release) - We could not install some updates because the PC was turned off. The laptop I am currently using was not turned off during install and I have made sure the active hours setting was set in the AM so I could install the updates.

    :)
