Microsoft visual studio "setup blocked"

Question

When I try to install Microsoft visual studio 2015 it gives the error "Setup Blocked". telling me:"The computer needs to be restarted before setup can continue. Please restart the computer and run setup again." after doing so it still doesn't work... I'm on Windows 10 Build 10130 this is the last bit of the log file:

and this is the full log

Answer 1

It seems that from Windows 8 onward shutting down doesn't actually turns the computer off, but rather hibernates it. That causes system files which the installer needed to operate on to continue being used.

You can turn hibernation off by running the following command as an administrator:

powercfg.exe /hibernate off

After running it, restart the computer and the setup should work. You can turn it on again by using

powercfg.exe /hibernate on
