Hmm. "unavoidable" errors that are now fixed; that's a conundrum :).

Well, I need to know what you are using the registry for; I have not
yet downloaded the sources, nor did I peek into the registry to see
what you had done to it.

I don't see how that is relevant to my point. I assume they have a
list of registry keys they installed, and they simply delete them.

Which is one problem with the registry approach; if I manage to
install version 3.2 and 3.3 of something, and then uninstall 3.3, 3.2
probably doesn't work any more.
