Try installing Fiddler Everywhere with an account that has administrative rights (this is a mandatory requirement), Also try running the failed command manually in your command prompt. 

cmd.exe /c ver

and let us know if you see the expected output, which should be something like

Microsoft Windows [Version 10.0.17763.1457]
