For some reason exejs is failing to find "cscript" (The default
Windows JavaScript script engine) in your system.

You can workaround that by installing latest Node.JS from here:

http://blog.nodejs.org/2012/01/19/node-v0-6-8/

(Use the MSI installer)

After you installed, close all the Command Prompt windows you have
open and open them again, which will update the PATH so node.exe is
accessible.

You can verify it worked by doing:

C:\>node --version
v0.6.8

That should be the output.

After that ExecJS should be working properly.
