Chocolatey version not working properly with VS Code launch.json

Hi,
I've been banging my head for the last few hours getting weird (unhelpful) error messages in VS Code, while trying to follow the setup instructions from you [here](https://github.com/jasongin/nvs/blob/master/doc/VSCODE.md)

I did the nvs installation using the [chocolatey package](https://community.chocolatey.org/packages/nvs) that is both suggested in the README.md but also on the official node.js site, when you go the "package installer on windows" route. The version installed through there is 1.5.2.

Now I don't know whether it is the older version used in the chocolatey package or the way it is installed through there, but I had no further problems when I uninstalled that and just used the 1.6.0 .msi instead.

I also had no problems doing a `nvs link latest` and then just using VS Code normally, the problem only arose when trying to configure and use a **launch.json** file.

I don't know if you guys maintain that chocolatey package yourselves or if it is some 3rd party, but given that it's mentioned in several places, it should probably either be scrubbed from those places or fixed.

Start with README.md and doc/VSCODE.md, then compare the Chocolatey 1.5.2 installation with the 1.6.0 MSI while reproducing the VS Code launch.json setup. Check whether the failure is caused by the package version or installation method. Done means the cause and supported installation path are established, with the affected references updated if needed.
