cordova add platform add/build windows8 error

Question

I am unable to create a cordova/sencha touch windows8 project. When adding platform windows8 via cordova platform add windows8 it gives me this error:

E:\testAndroid1\<app name>\platforms>cordova platform add windows8
Checking windows8 requirements...

The steps I am following are:

1. sencha app refresh
2. sencha app build testing
3. copy all files from /build/testing/ to wwww folder of cordova project.
4. Run platform add windows8 gives error.

Adding wp8 and android work fine and build and run as expected, the issue is only with windows8. Google didn't help either. Please tell what is going wrong.
