Windows 8 and 10 both lock up the c drive, you will likely have to add yourself under security for the drive, this will override the hidden or read only attributes. Right Click on the Chief Architect folder under programs > go to the Security Tab > add your username (if it isn't there) > Grant your username Full Control

Kbird1: Thank you for your input, my wallet was pushing toward the DDR3 as well.

I will be upgrading to 2015 Architecture as well as getting a new computer. I'm looking at a few different laptops. As a way of lowering system cost some laptop manufacturers have started paring new Graphics Cards with DDR3 memory. These are dedicated graphics cards and dedicated memory. The laptops themselves run on DDR4. For obvious reasons the version of memory the graphics card is using is hard to find. I'm wondering if anyone has had experience running large files using a graphics card on DDR3 memory. The computers I am trying to decide between are very equal in other respects, i7 gen 5 processor, 16gb of system memory, SSD, etc. Below are a few cards I'm considering: NVIDIA GeForce GTX 950M with 4gb of DDR3 GT860m 4GB DDR5 AMD FirePro M5100 w/2GB GDDR5 Nvidia® Quadro® K1100M w/2GB GDDR5 NvidiaQuadro K2100Mw/2GB GDDR5 Any help and input will be greatly appreciated.
