cant change access permissions

[Dutchmaster420]

i want to disable indexing on my raptor...but it says i dont have permission

i installed vista a week ago and i am the only user name

when i try to change permissions it gives me an error....this is ridiculous

why is this happening

Could you give us a click-by-click of what you're doing and what the error message is?
