ZTI error by using Role and Features

Hello,

I get an error by doing a task-sequence with roles and features. By selecting any role (for windows 8) I get this errors:

ZTI ERROR - Unhandled error returned by ZTIOSRole: Can not find path (76) ZTIOSRole 10-1-2013 20:02:01 0 (0x0000)
Litetouch deployment failed, Return Code = -2147467259  0x80004005 LiteTouch 10-1-2013 20:02:01 0 (0x0000)

How to fix this?

Thx
