Administrator Rights

I am unable to Immunize nor am I able to compete running spybot because it says I am not an authorized administrator.
I am the administrator of this computer. Can anyone help? Thanks

Hello,

Windows Vista might tell you that you are not being allowed to operate at the administration level of your computer.
You can solve this problem as follows:
Right-click the Spybot - Search & Destroy entry in your start menu,
instead of just left-clicking to start it.
Then, choose Run as administrator from the context menu.
You will find a screenshot of this problem in our FAQ:
