Riprep to .wim conversion error

[bjohn]

I'm trying to convert existing XP riprep images to .wim. It looks like it goes all the way through, but then it fails with the below error. I tried wdsutil and the console, both fail. Any ideas?

16:03:10: An error occurred trying to Convert RIPrep Image. 0x80070003

16:03:10: -> CEventBase::Register
