Summary: installer wakes up Windows File Protection
Initial Comment:
installing Python 2.3.2 on Windows 2000 SP4 induced the
Windows File Protection, presumably bcos an existing
system file had been replaced by an older version

While we're at it, I'd like to question whether we should be
shipping MS dlls at all. I'd *like* to question it, but have
never known how to <wink>: I don't know that it's necessary
to ship them, especially since we don't support DOS directly
anymore. OTOH, I don't know that no box out there needs
them either.

It seems I did include msvcrt.dll and msvcirt.dll from my
system directory, but probably the files from VC6 SP5 should
be included.
IMO msvcirt.dll is not used by Python, but msvcirt.dll uses
msvcrt.dll, so it makes sense to include both of these files
in the installer.
Here are the version numbers I found in the various installers:
Python-2.3.exe: msvcrt.dll - 6.1.8637.0, msvcirt.dll -
6.1.8168.0
Python-2.3.2.exe: msvcrt.dll - 7.0.2600.1106, msvcirt.dll -
7.0.2600.0
vcredist.exe: msvcrt.dll - 6.0.8797.0, msvcirt.dll - 6.0.8168.0
The vcredist.exe is from the VC6 SP5 CD.
I will include the latter files in the next installer
(2.3.3), and hopefully everything will be ok then.
Assigned back to myself.

msvcirt.dll was in the installer when I inherited it from Guido.
He probably inherited it from Mark (Hammond). If Mark can't
remember why it's there either, we should check all the .pyd
(not just python23.dll) for references to it. Assigned to Mark.

I *can* reproduce it - look into the event viewer, category
'System': File replacement was attempted on the protected
system file d:\winnt\system32\msvcirt.dll...
The windows installer tries (in my case) to replace the
version 6.1.8637.0 with 7.0.2600.0.
Looking at python23.dll's dependencies with Dependency
Walker, it seems that msvcirt.dll isn't required by Python
at all, so the solution would be simple: leave msvcirt.dll
out of the installer.
Why is it in the installer at all? Tim?

I couldn't reproduce this on a stock install of W2K SP 4.
If you're in a position to do so (you'll need the physical CD
media), could you rebuild your DLL cache? From the
command-line "sfc /purgecache && sfc /scannow" should do
this. After that, try to install python2.3.2 and see if sfc kicks
in again.
If you can't do that, you might want to see if the file
python23.dll somehow manually ended up in the %windir%
\system32\dllcache directory. As far as I know, thats the
only file that should be getting shoved into an area the sfc
cares about.
