I am excited about using Adapt Learning but can't get it to install correctly - I get a timeout when looking for the private key.  I am trying to install on a Windows 7 Professional 64bit

I have tried a lot of things but not a developer and so am struggling to figure how to generate a private key and point towards it.  Any help would be appreciated.  Below is the command prompt content

C:\AdaptLearning>cd adapt_authoring-master

C:\AdaptLearning\adapt_authoring-master>vagrant halt

Timed out while waiting for the machine to boot. This means that

Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.
