KeyUpdateTool.exe and XP SP3

[Nanookh]

Trying to legalize a number of PCs at one customer. Problem is that customer
has SP3 installed and KeyUpdateTool reports unsupported versions. When
uninstalling SP3, the tool works fine. Is there a new version of the tool
available? I have to do about 40 PCs, so would be very handy not to have
uninstall and re-install SP3

I'm having the same problem. My serial number is for something Pre-SP3 and I
can't activate my completely legitimate license on my laptop . I'll be
calling their licensing department in the morning and having them send me a
complimentary copy of Service Pack 3 Home full if they can't fix it without
forcing me to reinstall with a prior service pack. I slipstreamed SP3
thinking that was the smartest thing to do, it appears some stupidity (lack
of testing at Microsoft) has disproved that logic.
