XP SP3 and Windows Installer


Don Singles

I have just recently reloaded 2 systems using the manufacture supplied
Windows XP Pro w/SP2 disks. In both cases, when I downloaded updates from
Microsoft update, I was immediately prompted to install SP3.

I assumed this would be safe, but in both cases Microsoft Update was unable
to install any post SP3 updates after I installed it. I ended up
uninstalling SP3 running Microsoft Update agin, but this time shoosing to
install other updates rather than SP3. In both cases, I was prompted to
install a newer version of Windows Installer (to V 3.1). After installing
this and THEN installing SP3, I had no issues.

Tonight I started on a 3rd system and skipped SP3 at 1st. I chose to
install other updates and then SP3 and everything worked great.

My question is, is this a common problem?

Shouldn't I be able to go straight to SP3 without this extra step or am I
missing something (or is MS Update supposed to be prompting for the Windows
Installer Update BEFORE SP3?)

SP3 requires that either WinXP SP1 or SP2 be installed.

That being said, CrystalBall© sez...

Updates are not installed successfully from Windows Update, from Microsoft
Update, or by using Automatic Updates after you repair a Windows XP

NB: Also applies to clean installs, upgrade installs, and Recovery installs.

Just thought I'd mention that if you would go to the Microsoft download site
Windows Installer 4.5 is available as a download. It is an after SP3 item.
