think something may have been misunderstood.
You dont need to uninstall it, but it wouldnt hurt to do so. Though you can uninstall it by going into wii settings, saved blah, channels, and erasing it.
As for HBC, i'd just use 1.0.1. You'll probably need to google it, or grab it from inside another older package. The official site only has 1.0.3.
I know the files guy uses in this youtube tutorial include 1.0.1. So if nothing else, you can just grab it out of there.
