Summary
I tried 3 times to download it and it told me three times: The expected version of Microsoft office 2000 was not found on this System. You just plain don't have it.
Do *NOT* install this patch ... NEVER!!!

Summary
This is really bad. I made myself a custom Outlook script to block spammers. I installed the patch, now my script does not work anymore and I am flooded with spam ... GREAT! If you install this patch you will have to completely reinstall Outlook in order to get back to a normal world. If you installed Outlook as a part of Office, you will have to reinstall Office entirely.
I have always liked Cnet for its variety of downloadable programs.

Summary
Unlike Outlook Express which can allow users to select "Do not allow attachments to be saved or opened that could be potentially virus", this new update from Microsoft doesn't implement this, unless u have a 3rd party software like 'Outlook Security Addin' (freeware) or the 'Xenos Outlook Security Extension'. Otherwise I am glad my collegues with the patch are guranteed protected from the W32.Mydoom.A@mm virus attacking wildly in our office PC, compared to those without the patch, still attacked by it (and causing Norton to pop up and freak them) Please implement such features also like the Outlook Express, Microsoft.
Arggghhhhhh!!! Gates, I hate you for allowing tosh like this to be produced.

Loosing your email attachments is bad enough, but not being able to uninstall is typical MS. The fix if you have SP3 does work though.
Oh my!

An example of lazy programming, with Microsoft opting for the quick-fix approach... I don't know about others but it removed zip attachments as well without any notification... pretty dodgey in my opinion.
