ATTENTION to Language specific installations:
For example:
You have a native language installation. Win2003 SP1 GERMAN
and you are using the standard Virtual Center installation. This is the english Version.
THEN your PATH NEED to look like this:
<ALL USERS>\Application Data\VMware\VMware VirtualCenter\sysprep\<os>
means for this GERMAN case
C:\Dokumente und Einstellungen\All Users\Application Data\VMware\VMware VirtualCenter\sysprep\svr2003
be carefull the Folder Application Data remains english. IT IS NOT "Anwendungsdaten".
Hope this helps.
Regards,
