Error when npm is not installed in PATH

Seeing this error:

📦 Packaging current Fiddle...

Error: Could not find npm. Fiddle requires Node.js and npm to compile packages. Please visit https://nodejs.org to install Node.js and npm.

On Windows 10 x64. Using Fiddle app 0.6.0 with Electron v5.0.0
NodeJS installed to C:\Program Files\nodejs but not on path.

In Fiddle console I see this error below.

Any ideas?

Thanks
