I suppose that you are using Android 4.4 and not Android 4.4W or 4.4L which are not yet supported. And you should have made recently an update of the Android SDK tools to version 23 (you can verify by opening the SDK Manager)
Google has modified in this release the way the tools are organized and this made MTWW regressed when instrumenting.
There is a workaround: copy <android-sdk-dir>/build-tools/20.0.0/zipalign[.exe] to <android-sdk-dir>/tools.
