Upgrading to Professional - After SP2 has been installed

[Mike]

Hello.

I am attempting to upgrade to Windows XP Pro from Home edition. The error
it tells me is that the version of windows I'm trying to install
(professional) is older than the currently installed version.

I've recently installed SP2 for my home edition and was wondering what could
be causing this. Any suggestions.

Unless SP2 is integrated into XP Pro, then one cannot
upgrade an existing XP Home w/SP2 installation using
a non-SP2 version of XP Pro. What you need to do is
create a SP2 "slipstreamed" version of XP Pro, then use
the new CD to upgrade over XP Home w/SP2.

You have two options:

1. Uninstall SP2 from XP Home, then upgrade to XP Pro.

or

2. Create a SP2 slipstreamed version of XP Pro (preferred)
and use the new XP Pro w/SP2 to upgrade.

Either one of the following utilities makes slipstreaming
(integrating) SP2 into Windows XP a breeze:

Hi,

You need to uninstall the service packs before doing the upgrade.
