When installing service pack 1 this error appears; "Setup has detected that the build version of the system installed does not match the update you are applying to it.
You can only install this update only on Build 2600".
I cannot install the service pack at all. What could be wrong?

Could you check your build number, as this seems to be wrong. Goto run, type cmd and in the command prompt type ver. The last numbers indicate the build number of Windows. It could be that you're running a RC or beta. If so, the build number (last four numbers of the version) will be lower than 2600.

In this case, you first have to upgrade to a build 2600 version (or find the reg key that holds this value), and then run the SP

Hope this helps

Are you sure that your version does not include service pack 1 already?

My XP Pro without SP1 installed is 2600.

Does SP1 show up on the list when you run Windows Update?

The build number is at registry location:
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
