Unable to install SDK Platform 4.0.3

Question

I'm trying to install the SDK for android 4.0.3 but I get an error and it does not download nor install.

Unexpected Error installing 'SDK Platform Android 4.0.3, API 15, revision 2': org.eclipse.swt.SWTException: Widget is disposed  

This is the error.
Anyone know how to fix it ? :)

EDIT:
Problem fixed, don't know why nor do I know why the problem even occured.

You need to run SDK Manager with Administrator Permission.

Try Run as Administrator by right-click on it
