799940 2009-08-10 07:51:00 I have a Dell laptop with a COA Windows XP Professional 1-2CPU
I used my Windows XP Professional with Service Pack 2 to install windows
but
it wont accept the COA code.

Why?

799941 2009-08-10 07:51:00 You probably have an OEM COA with a retail disk, or the other way around. You need to have a matching disk.

If you don't have a matching one, you can find a guide here (freepctech.com) on how to change yours so it will work - note however that you still need a valid key.

799942 2009-08-10 08:02:00 XP Pro differs to XP home regarding Prduct keys - Generally you can use any OEM Hm key on a HM OEM CD.

With Pro - you have to have the right key for the CD - Meaning, even if you have a OEM CD, and a OEM Key with pro it still may not work.

I actually have 5 different OEM XP Pro CD's I sometimes use when people dont have the original CD, But do have the COA, not every key works with every CD.
Some times its pot luck as to what CD to use, other times I have an original Dell XP Pro CD, that 1/2 the tme works with Dell keys, but nothing else.
Its basically try to install on a small drive ( 4.3GB) to the point of installing the key - if it works :thumbs: - if not try another CD. 1 out of 5 usually works.

BTW - the 1-2CPU doesn't work with my Dell CD.

I've actually looked at the setup as per Erayd's link - and they are all the same, yet some just dont want to play nice.:illogical
