You do not have permission to view the current permission…

Dear Members,
recently I have upgraded my system from Windows XP to Windows Vista.
I wish to set access control for some special folders.
But when I try to change the permission settings the following message appears; "You do not have permission to view the current permission settings for Properties, but you can make permission changes.".
Is this because I haven't administrative control or something else.
How can I resolve it?

Error:
You do not have permission to view the current permission settings for Properties, but you can make permission changes.
Sincerely,
Diana Ana
