Error 0x800736b3 when installing KB4074588

Hi,

The 0x800736b3 appears to be linked to .NET Framework 3.5.

I suggest you to follow the below steps to check whether the .NET Framework 3.5 has been installed or not.

• Press Windows+X and then select programs and features.
• On the left hand side click on the option turn windows features on or off.
• Check whether the “.NET Framework 3.5” has been checked or not.
• If not check then I suggest you to check it and then install it.
• Restart your computer and try installing the KB4074588 again.

Kind regards,

Leon

I ran the command and restarted 3 times. I still see the update as "Awaiting restart" in the list.

Please note that the error is 0x800736b3 and not 0x80070bc2 as you wrote.
