If you are referring to the .../lazarus/components/lazutils/lazutils.lpk package (not some third party package of the same name) then this is auto-installed by Lazarus and should not be installed manually. It provides utf8-related, xml-related, avglvltree, lazlogger and many other facilities. It is present out-of-the-box in a default Lazarus installation.
Indeed, I'm not sure how you fooled the IDE into installing it 'twice', but perhaps you have an older version somewhere?
I suggest you uninstall Lazarus entirely, clean and remove the former lazarus folders and reinstall Lazarus. And refrain from trying to install any base Lazarus packages. The installer (or OS package manager) does all that for you.
