Attached is a copy of these files, place them into the locations above with respect to their architecture type.
Once the files are in place, we need to refresh the package snapshot data, resync the packages and rebuild your WinPE preboot. Do this by doing the following:
Open C:\ProgramData\Symantec\SMP\Snapshot
Find the {374e1c49-4f58-4f5c-8d51-07a30f0d44ad} SIG and XML files, and delete them
Open Windows Task Scheduler, and within the Task Scheduler Library, run the NS.Package Refresh
Confirm when the Package Refresh finishes that there are new SIG and XML files with the same guid in the location in step 1
Sync the BDC package amongst your package servers
Regenerate your WinPE environment
