4.) Place builder folder on C:
5.) Run builder as Admin
2.) Also make sure you are using ISO downloaded from below linked tool:
1.) Try to use 8chars or less in builder folder and source folder names (Also placed on ROOT)
3.) Disable NOD32 completely (Eset) during build (Probably not needed, but best for testing, since you mentioned you might as well)
Do all 5 of these, if you still experience errors, let us know in this thread.
Your suggestions, for which I thank you, do not explain the reason.
