Norton utilities

Hi ,

 

I have just downloaded the trial version of Norton utilities (v14 ?) and when i try to install it i get the message -

 

 'For security purposes, this program will not run while system debuggers are active. Please remove or disable the system debugger before trying to run this program again.'

 

Can anyone please tell me how to do this ? !!!!

 

Thanks in advance for any help you can provide.

 

(I'm running windows 7 x64 on a dell 1535)
