How do I install mailparser module via npm on Windows 7 x64?

Apologies if there is something obvious I'm missing, I've actually never encountered this error before using npm:

C:\work\spark3>npm install mailparser

I have tried the following on my Windows machine after scouring the web:

• Reinstalling Node.js
• Reinstalling Python 2.7
• Ensuring the path for Python is set
• Updating npm
• Installing Visual C++ Express 2010
• Installing node-gyp globally
