OK. One question: why CRT doesn't get installed as regular files near to
the python executable? That's how I usually ship it, but maybe Python
has some special need.

I proposed an alternatives because I read you saying: "The tricky part
really is when it breaks (which it does more often than
not), in which case you need to understand msi.py, for which you need to
understand MSI". Which means that maybe everybody *has tools* to build
an installer today, but only a few people have the required knowledge to
really do releases on Windows.

So I believe that switching to an alternative that doesn't require full
understanding of MSI and msi.py would probably low the barrier and allow
more people to help you out.
