ERROR:
c:\\Users\\dhawal.vora>vagrant ssh
`ssh` executable not found in any directories in the %PATH% variable. Is an
SSH client installed? Try installing Cyg
With Windows 10 I also couldn't get the 'set PATH' option to work. But when I amended the PATH variable through System Settings and started a new command prompt it worked fine.
Also, putty worked perfectly after I read the screen which told me to use a username of 'core'.
'core' was a requirement of my configuration which was trying to launch CoreOS.
