I see, thanks.

Is the service named Remote Procedure call running and set to automatic?

Please try installing the latest feature update manually and let us know.

Answer 2

I ran the registry key you sent, it said it applied the changes, but the process still won't start, it still tells me access is denied

Answer 3

Thanks. I am troubleshooting from scratch so let us see if that helps.

Can you try restoring the entire service using this Registry key?

Answer 4

in the registry editor the service is already assigned the value 2, but it is simply not running

Answer 5

Hi Olivia,

I am Sumit here to assist you with this question.

What happens if you change the value in the Registry to 2? Do you get access denied?

It would be 4 if it is disabled.

We can also try to update manually as an alternate.

Keep us posted.
