Applications don't install from OSD after 2012 SP1 upgrade

Question

After upgrading SCCM 2012 RTM to SP1, then to CU3 (to fix a PXE issue), my OSD task sequences no longer installs any applications after the OS.  Win7 installs with all drivers, the PC is added to the domain and the correct ConfgMgr client version is installed
with a healthy connection to SCCM.
However the C:\_SMSTaskSequence folder remains with the 7GB WIM file and none of the 12x applications installed.  A task sequence with the applications works when run from Software Centre.
Here's a link to the logs:

Thanks for checking it out.  Those errors are old entries from a year ago.  Not sure why they are still there; current issue date is 14-01-2014.  Network Access account is set and permissions are correct.
The TS logs look fine up to after installing the ConfigMgr client.  It then kicks off TSMBootStrap.exe:
==============================[ TSMBootStrap.exe ]==============================
Command line: "C:\Windows\CCM\TSMBootstrap.exe" /env:Gina /configpath:C:\_SMSTaskSequence /bootcount:1
Logging successfully initialized.
Resuming Task Sequence in Full OS
It then logs a whole bunch of:
Failed to open key Software\Microsoft\SMS\47006C006F00......  \SMSTS
then ends it with Exiting with return code 0x80070002 which is:
"The system cannot find the file specified."
And that's the end of the TS.  I need to find out what file it's referring to.  TSMBootStrap.exe exists in the correct path.
