How to re-install windows installer

[Guest]

Hi
am having lots of problems with Windows Installer ( have tried all the known
fixes but the problem remains)
Can I uninstall SP2 and reinstall it without causing too much distruption to
my system
I am right in beliveing that windows installer is in the SP2 update.
Not sure what causes the problems but the last time (about 2 months ago) I
ended up reinstalling Windows XP Pro
Thanks

I take it you've already tried KB884016-v2-x86.exe ?

Sadly Yes

I have exactly the same problem where I cannot install, update or deinstall
anything which uses the Windows Installer ( cannot even update Windows
itself...). If a program or a game is updating through its own system (like
Nod32) it updates perfectly.

If I try to deinstall those programs in belief that I can update them by
downloading the newest available software, it says there is an error in
Windows Installer and that I need to contact further customer support (which
I have done now thrice in vain). I have so far downloaded 2 different Windows
Installer versions and over three different Windows XP patches and updates
either related to XP Home Edition or SP2.

I am currently using Windows XP Home ED SP2. I have more or less learnt to
live with this problem since I do not use that many programs however, when
even good old MSN stopped working because I need to download the new version
in order to continue to use it... this is getting incredibly silly. I cannot
even download and install the new version for Christ's sake... and I can't
deinstall it either...

The only solution I see for now is to deinstall or using some kind Windows
repairing tool since it seems like not even the updates themselves seem to
actually install (it kinda goes somewhere like "preparing to install..." and
at some point it says it is finished despite it didn't show any process
whatsoever).
