Privilege to Uninstall Apps

Hi,

I tried uninstalling some apps from CCleaner, but an error message keeps popping up that I don't have enough privileges to carry out the operation. I am logged in to my main account on my Mac.

Help!

Same issue here, logged in as administrator but just get the "You do not have privileges to perform this operation" message.

Is this a bug or do I need to change a setting somewhere?
