Create app error on windows 7

Just did a fresh install of meteor, but cannot create app. Here is the error message:
C:\apps>meteor create app2

I had this error before I uninstalled meteor. Though a fresh install would solve the issue but sadly no. Could someone help me out? Thanks.

Update:
Apparently the app ‘app2’ was created. I can run it. But the error message is still annoying, especially right after a fresh install.
