I have XP and that you want to upgrade to XP Pro, but Windows will not let me.

My office recently crashed and I replaced the windows XP home that came on the machine.  I also have a copy of XP Pro upgrade that I want to install because pro allows me to office remote host and does not House.  These are both legally purchased copies.  When I try to upgrade to pro it won't let me and warned me that the original desktop version is newer than the upgrade.  I don't like the age I want the features I paid for the upgrade.

All solutions?

1. determine what service pack is now installed (right click on desktop and select properties).  You must have service pack 3, but if you have recently reinstalled Windows XP Home Edition, you may have neglected to update at this point.

2. either consider that if you have a CD for an earlier version of Windows (98, Me, 2000), you can do a "clean install" of XP Pro by booting from the CD-ROM to upgrade XP Pro and then insert the qualifying product CD when asked.

3. If you want to 'upgrade' to protect the applications and data already installed on XP Home, first back up your data (just in case).  As indicated in the error message, your upgrade installation CD must be equal or superior to your current installation of XP Home service pack level.  Compare the service pack level of your installation of XP Home (see 1 above) and the level of service pack of your XP Pro installation CD.  Then create a CD slipstreamed that combines the real CD XP Pro you have with the correct service pack.  There are many instructions for this on the web.  See http://lmgtfy.com/?q=slipstream+xp

I suggest that you use nLite (see the first hit in Google search above).

If your XP CD Pro has NO service pack, you must first integrate the SP2 and then sp3 wake in this.

If your CD of XP Pro at service pack 1 or 2, you can integrate service pack 3 (for example, you can go from 1 to 3 without add 2).
