I'm not really sure how to run the prerequisites. I googled it and in one thread on steam, somebody said you should run redist. I searched the xcom folder and found vcredist_x86 and vcredist_x64 and ran them both. I also ran directx. I did not find any of these files in the Life is Strange folder.
Is there and option in steam to analyze the system and also compare them to the game requirements for each game? because that's what I need I think.
