Vagrant Box Add failed

In fact, the previous period also appeared this problem, and later thought it was the cause of the computer, nothing.
I'm faking it. virtualbox, vagrant, and then try vagrant box add laravel/homesteadand failed; and then I tried the official recommendation of the old way vagrant box add laravel/homestead https://atlas.hashicorp.com/laravel/boxes/homestead, or failed, I finally downloaded the box and tried to add it locally vagrant box add laravel/homestead virtual.box, the same failure, and three times the same error:

D:\Homestead>vagrant box add laravel/homestead virtualbox.box==> box: Box file was not detected as metadata. Adding it directly...==> box: Adding box 'laravel/homestead' (v0) for provider:    box: Unpacking necessary files from: file://D:/Homestead/virtualbox.box    box:An error occurred while downloading the remote file. The errormessage, if any, is reproduced below. Please fix this error and tryagain.

Is the reason why the virtual machine VirtualBox? Is that why I didn't install it or the version?
Ask the great God to tell!

It turns out that Google and StackOverflow are good friends of apes. Forehead, pure spit groove.
StackOverflow There are a few similar problems, I used one of the methods to solve, is now posted out for the needs of small partners reference.

I downloaded
cUrl x64 with SSL
and replace it with the curl.exe provided by Vagrant.
In and words, I copied the Curl.exe to
C:\HashiCorp\Vagrant\embedded\bin
Now it ' s working perfectly

The answer to the Chinese language is not found any solution, and later with Google in the English site to find solutions: encountered even local can not add box, to install the VS2010 run library. Vagrant's error is really unscientific, this level of false hints, people have no sense of the mind. Because the general use of vagrant people are basically developers, the basic running library will be installed on the first time, the novice encountered this situation completely puzzled, let alone Google to look over several pages of the answer.
