Issues when i installing Cordova using npm install

I have just got started with Ionic and as much as it is awesome I am having a few issues installing the Cordova side of things.

when I try to install Cordova using npm install -g cordova I get the following errors and cannot get past it. Has anyone else hit this issue?

are you running it from CMD started as Administrator or just normal (click on menu item)? Try starting CMD by right clicking on CMD (Command) in Start menu and selecting run as administrator.

Reason its saying in the errors no permissions to create directories

Thanks for help @gmlogan
