for some reasons I cannot install Python 2.5.1 using the default MSI
package which may be found here This only
happens on two of my PC's at work but I cannot reproduce it at home.
The only difference I could find between those Windows is that the
PC's at work are connected to Active Directory domain whereas my home
machine isn't. I tried to install Python as a domain user and also
as a local administrator but every time I encountered the very same
screen (see attached file objectbrowser.png) and then the installation
process rollbacks. I'd like to investigate
it further but I have no slightest idea where to start. Do you perhaps
have any suggestions? It's all Windows XP SP2.

Can you please run

msiexec /i <msifile> /l*v python.log

then compress python.log, and attach it to the report? Thanks.

Done. Attached in I've also noticed something strange here. says the MD5 sum should
be a1d1a9c07bc4c78bd8fa05dd3efec87f but the MD5 client I'm using
( tells me the file's checksum

D:\tmp\python_install>md5 python-2.5.1.msi

MD5sums 1.2 freeware for Win9x/ME/NT/2000/XP+
Copyright (C) 2001-2005 Jem Berkes -
Type md5 -h for help

[Path] / filename                              MD5 sum

What does it mean? Is it my client fault?

Hmm, on a home PC the checksum's correct, it's
a1d1a9c07bc4c78bd8fa05dd3efec87f. Assuming something is wrong with
my download at work, is it possible for an MSI package to start the 
installation even when package is corrupted?

Anyway, tomorrow I'll try to install the MSI I downloaded at home.

I can confirm that the correct checksum of the file is what the web page
says. So it seems that your web browser corrected it during the
download. That, typically, is caused by the web browser perform a
conversion of line endings in a binary file, so it would indeed be best
if you try with a different copy, or a different web browser.

"your web browser corrected it"? Do you mean "corrupted"?

I think we can close the issue (although I seem not be able to do that).
The installer works just fine now I've downloaded it using another
browser. For future reference - the former one was Mozilla/5.0 (Windows;
U; Windows NT 5.1; en-US; rv: Gecko/20071030 SeaMonkey/1.1.6
