Yep, it just means that your environment variables for that folder are missing, but it's an easy fix.
Go to
My Computer, Control Panel, System and click on the
Advanced tab.
At the bottom of the window, click on
Environment Variables.
Under "System variables", you will see an item called "Path". If it's not there, press
New, however, every system will have this by default. Click on
Edit.
Scroll to the end of the
Variable value. Each value is seperated by a ;
At the end of the line, add
%SystemRoot%\system32
Press
OK, and away you go!
