Multiple instances of Python are routinely used on all flavors of
Windows without problems (at the moment, I have 4 on my XP box, and
often run 3 simultaneously).

Then you need to ask on Zope and TSW (unsure what that is) lists about
why those applications are fighting with each other.  Asking here is
like asking on a bash developer's list because you run two apps from
the shell that insist on having different PATHs.  There's nothing bash
can do about that -- and the question is better addressed to a bash
user's list even if you think there should be.

Well, Python isn't forcing the use of TSW, and Zope certainly isn't,
so if I were you I'd ask the TSW developers what they're up to.  I
have no idea how they manage to change Zope's Python's idea of what
exec_prefix should be.  Zope sets no environment variables or registry
entries related to Python, and Zope runs happily without interfering
with a user-installed Python, so TSW is your hangup.
