Hi Oskar

I'm no vagrant expert, but I get a similar error if I run vagrant up when the authoring tool files are missing but the vagrant box has not been installed.

For example if I want to start afresh and I have uninstalled the vagrant guest machine with vagrant destroy command and then try and reinstall with vagrant up. In that case you would need to copy back all of the authoring tool files.

Another gotcha is not running command prompt as administrator.

Not sure if that's of any help.
