Hide Launch Bar "Advisor"

[LeeNash]

Hi,

I'm trying to hide the ability to see the "Advisor" option on the launch bar once a user is logged into Cognos Express.
I've gone into Administration and clicked on the security tab then to Capabilities but I'm not 100% sure which one is which.

Could anyone possbily point me in the right direction to hide the Advisor option?

Thanks in advance.

Regards
