Cannot install Fastboot on Windows

When attempting to install Fastboot on Windows 8.1, I get the error listed below. I’m not certain if this is an issue specific to running Fastboot in Windows or something else. Any suggestions for quick fixes I can try on my side would be appreciated.

Error message:

ember-fastboot-server@0.5.4 postinstall: `scripts/is-not-legacy-vm || npm install contextify@^0.1.11`
Exit status 1

[tomdale]

Solved once https://github.com/ember-fastboot/ember-fastboot-server/pull/48 is merged

[jakedetels]

Issue is resolved. Was able to successfully install from Github (NPM still needs to be updated). Thanks, @tomdale for the rapid resolution.
