i don't have antivirus installed

Edit:
will no my system is not broken how i know that ? will it happen that i have dead space which is repacked in the same way dark sector is repacked and it's working even if there is an antivirus anyway i did as you said and disabled Windows Defender and tried again but to the same result

Edit #2:
it's a new build i was saving money for
Intel Core i7-3970X Extreme Edition Sandy Bridge-E 3.5GHz LGA 2011 Six-Core Processor
ASUS Rampage IV Extreme Socket 2011 Motherboard
G.skill RipjawsX 16GB (2 x 8GB) DDR3 2133 CL9 1.6v Dual Channel Memory Kit
Gigabyte GeForce GTX TITAN OC 6GB GDDR5 Windforce 3X
Windows 7 Ultimate X64

Edit #3:will as i said before every thing was done according instructions by Peterf1999 i don't see anything wrong only that damn DS_arc.exe is not unpacking by it self
thanks anyway buddy
