I tried do a lot of things: execute as adm, reinstall. My system is 64-bit and this is my path:

C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\xampp\php;C:\ProgramData\ComposerSetup\bin;C:\Users\Cássia\AppData\Local\Android\android-sdk\platform-tools ;C:\Program Files\nodejs\

Seeing the path that you have provided, it still has the path for npm missing. I recommend you to uninstall the node from control panel, restart your device and install the correct version of node. For me, node version 5.3.0 is working as well. However, installing Node version 0.10.38 may do the trick for you.
My path:

C:\Program Files\Java\jdk1.8.0_65\bin;C:\Program Files (x86)\Android\android-sdk\platform-tools;
C:\Program Files (x86)\Android\android-sdk\tools;C:\Program Files (x86)\apache-ant-1.9.6-bin\apache-ant-1.9.6\bin;
C:\Windows\System32;C:\Users\office\AppData\Roaming\npm;
