Having troubles with Angular 6 and node sass on Windows 10 x64?

I was getting all kinds of errors after upgrading my project to Angular 6 on Windows 10 x64, including errors on node sass.
These errors were resolved after I removed the x64 version of Node en installed the Node LTS 10.13.0 x86 (32bits) version on Windows 10 x64.

Errors ng build: Exit status 3221225477.
