Installation error

Hi there, i'm having an installation issue:

(All software Versions are on the error message including SO)

```
gyp ERR! build error
gyp ERR! stack Error: `C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe` failed with exit code: 1

```
I have instaled build tools in an elevated powershell console using

`npm install --global windows-build-tools`

Wich promptly says that Python and VisualStudio Build tools installed and is configured without problems.

Anyone had the same issue? Can share some insight?
