Vagrant, can't download box

Question

not sure why I'm having this issue but I can't add vagrant boxes.

Using windows 10, tried on powershell and simple command prompt. same issue. It's a relatively fresh install of windows. Maybe I'm missing some required package?

first i tried this command:

vagrant box add hashicorp/precise32

and got the error:

The box 'hashicorp/precise32' could not be found or
could not be accessed in the remote catalog. If this is a private
box on HashiCorp's Atlas, please verify you're logged in via
`vagrant login`. Also, please double-check the name. The expanded
URL and error message are shown below:

URL: ["https://atlas.hashicorp.com/hashicorp/precise32"]
Error:

So I downloaded the box manually and tried this:

vagrant box add base64 file:///D:/downloads/vagrant_boxes/precise64.box

And got this error again:

==> box: Box file was not detected as metadata. Adding it directly...
==> box: Adding box 'base64' (v0) for provider:
    box: Unpacking necessary files from: file:///D:/downloads/vagrant_boxes/precise64.box
    box:
An error occurred while downloading the remote file. The error
message, if any, is reproduced below. Please fix this error and try
again.

The libraries on current version (as of this date) OSX don't support the version of curl bundled with Vagrant 1.8.7. I installed 1.8.6 and everything worked like a champ. To test this theory:

cd /opt/vagrant/embedded/bin
./curl --help

If you get a 'normal' reply than you should be fine or there's something else wrong.
