Hi Mr.Barre,
· What is the version of service pack installed on the computer?
When you install language packs on the computer it would usually prompt for the Windows XP installation CD.
Since you do not have the Windows XP CD I would suggest that you provide the below location when it prompts for the CD and check if it helps.
C:\windows\ServicePackFiles\i386
