I have added the fog.drivers script from the tutorial site: https://forums.fogproject.org/topic/8889/fog-post-install-script-for-win-driver-injection

It looks like the script attempts to run, but indicates some errors preventing the script from running. (see screenshot). At first I was running a modified version of the script, attempting to simplify the machine identification, but I have since tried running the script as it came from the FOG tutorial and have the same result.
