WARNING - unable to set working directory: (-2147024894)

This error is caused when the working directory no longer exists that is assigned to the application being installed. It would be nice if MDT published which app it is, but it does not. To find the application, open up the BDD.LOG file. Search for the error message. You will see the directory it is trying to access on the line above. Just a few lines above, it should also display the app the directory is associated with right above the ################ line .
