Add-on Utilities were created to make managing your add-ons far easier. Especially for update purposes, and installation purposes. However, some times they have thier problems. Some of them include sometimes not installing to the right place, updating to an outdated add-on, or just not finding the add-on.
A recommended practice would be to install all of the add-ons by hand, and then run a utility. this will allow the utility to find all of the add-ons at that point and self configure itself for the most part. Below are two add-on Utilities that are the most Useful to date.
