Titanium Alloy project fail to build

Question

When attempting to build my app in Studio on Windows 7 the build fails with the following error:

[ERROR] Application Installer abnormal process termination. Process exit value was 1

I got to command line and attempt to run then it fails with more information:

[DEBUG] :  Detecting modules in C:\ProgramData\Application Data\Titanium\modules
events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:1011:11)
    at ChildProcess._handle.onexit (child_process.js:802:34)
TRACE  | titanium exited with exit code 8

I don't know what is the reason for this. Any help?
