Apparently Dragon Age Inquisition won't even launch with any of the Pentiums, and requires a CPU with at least 4 threads to even play, so AMD A8 APU or Intel Core i3 or higher basically. Whether that is a bug that will get patched out later, or an intentional design choice on Bioware's part I'm not sure. At present, you cannot play, and Bioware may well decide not to fix this as the minimum requirements for the game did call for a quad core CPU.
