If you are experiencing an error where the game will close down when you attempt to open something in the game that would require the file explorer please follow these steps.
Download and run the exe in the file linked below (it contains a program called ShellExView)
https://www.dropbox.com/s/5d8k0ls9uqv3asr/shexview-x64.zip?dl=1
This is going to give you the option to disable some shell extensions - look for two files
DBROverlayIconBackuped.DBROverlayIconBackuped Class
DBROverlayIconNotBackuped.DBROverlayIconNotBackuped Class
Find these and disable them and then run the game. If you do not have those files and you have an Alienware computer look for two icon overlay handlers called Alien Respawn and disable them
