4.15 runs a blank project but crashes with FPS

Hi! I tried to open a new FPS template project with UE4.15 but it crashed. So I opened a blank project successfully and added the FPS Blueprints with Add New->Feature Pack and changed the GameMode to FirstPerson. But the project crashed when I clicked Play.

My laptop’s specs are - Dell Inspiron 15 3000 series, 4GB RAM (I’m aware this is low, but 4.16 works fine), Core i3 2.5 GHz, Windows 8.1 64-bit

Is it a RAM issue? Does 4.15 require a lot more RAM than 4.16, especially while running FPS?

Two logs I found in the Logs folder:
Unreal 4.15 Blank Log 1 - Pastebin.com,
Unreal 4.15 Blank Log 2 - Pastebin.com
