Hi peter.wood,
Looks like the package is attempting to install, but is failing. One thing that makes provisioning troubleshooting a bit harder is that we have our "handlers" (the guys that do the actual work) depend on other handlers, but then the logging that the other guy does is in his own log.
I know that's confusing, but what I mean is that we call sdclienthandler.exe (the guy that processes SWD Packages for us) and have him do the work to install the package, because he already knows how and that's easier than trying to make HiiClient know how to install packages. The end result here is that the log that should have information about what happened when we installed the package is in the sdclienthandler.log file. It would be in the ldprovisioning directory until provisioning cleans up, at which point it should be moved to the Windows\Temp directory. Does that log give any insight into why the package failed to install?
