Summary: Registry not updated by 2.4b1 installer

Initial Comment:
Running the python-2.4b1.msi installer on Win98 SE
appeared to proceeded as expected. However, the
registry appears not to have been updated and any
add-on Python library installers are still asking to be
put in my old Python 2.3 directory, effectively
preventing me from using those libraries with 2.4b, or
any scripts that rely on them.

Ok, maybe the summary is misleading. The
HKEY_LOCAL_MACHINE\Software\Python subtree appears to exist,
with PythonCore and Pythonwin subtrees under it. Under
PythonCore is a 2.3 subtree and a 2.4 subtree. This implies
the installations work side-by-side. I found nothing
explaining whether to uninstall a previous version or not in
the docs on Python.org, or whether it is possible to upgrade
a previous version by installing into the old directory,
etc. In particular http://www.python.org/2.4/msi.html avoids
this issue. I had guessed that maybe the move to some sort
of official packaging system was because it would enable
these automatic updates, somewhat akin to RPM, but obviously
not.

I can't comment on how the installers for add-on libraries
on Win32 are made (although it seems to use a standard
package), only that I get no option to install them into the
2.4 directory, at least given the 3 I've just tried.

I cannot reproduce this on XPSP2. Can you please use
regedit.exe to find out
a) whether HKEY_LOCAL_MACHINE\Software\Python exists, and
b) if so, what its subkeys are? In particular, is anything
about 2.4 present?

If installers choose 2.3, it might be that they have
extension modules which need to be recompiled for 2.4, in
which case the installer specifically looks for a 2.3
installation, rather than the latest installation.
