Can't Install KB3191566 (Powershell)

[dogz4321]

For some reason, no matter how I try, I can't update Powershell.

What I'm trying to actually do is install Chocolatey, and Chocolately wont install with Powershell version 2.

When I try to install KB3191566 to update Powershell, it stays in the Initialize section for a long time and then eventually just poofs and says its unable to install it without any other information.

When I run sfc /scannow, it tells me there is some corrupt files but it was unable to fix some of them:



SFC Fix says it didnt have any issues:

Any help would be really appreciated.
