Every time I try to install the game I choose more options so that I can install it on a different partition than the default C but whatever I choose it starts installing on C and towards the end of the installation it stops and gives me the following message: Failed to load DLL: Firewall Install Helper Setup will now terminate. Why can't I install it on a different partition?
