I tried to install ionic and cordova (like many times before - without any problem) and it hadn't worked.
There's always this:

```
npm ERR! Windows_NT 6.3.9600
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\n
pm-cli.js" "install" "-g" "cordova" "ionic"

npm ERR! code ENOENT
npm ERR! errno -4058
npm ERR! syscall rename

```

I tried several node.js versions and npm cache clean. But sadly nothing worked out.

Here are some lines from the npm-debug.log:

```

Have anyone an idea what might be wrong? Thanks!
