You may have used a non-standard/genuine ISO or may have installed applications you should'nt have. Some applications may cause Sysprep to fail
@KFeri Try it with untouched ISO. Then you will see it work without issues, then use NTLite on that ISO and then do removals one by one. You probably removed something that is needed in this process.
I thought if I post the setting, you might be able to look and see the error... Instead: I'll look at it one by one and try it one by one. Well, I could have done that myself, but the very reason I asked for help was to avoid having to do that. But I get it: everyone is pressed for time. I'm not holding anyone up. Have a nice day.
