Any news about the reported issue from Ladewig-Wustl he posted under en.community.dell.com/.../19979685.aspx ?
He reported that HAPI is not loaded if you call cctk.exe from outside the directory where cctk is located. We're able to reproduce exactly the same behavior (set BIOS settings through a cctk.exe command line in a task sequence under SCCM). Tested with the latest CCTK version 220.127.116.11.
