Hello, I bought Emergency 2012 from Gamestop, and when I go to update I get Installdir not found.There isn't an update button in the game, so I can't update via in-game. The Game is located under program files(x86)----Indie Games----Emergency 2012. I don't know why its under Indie games, I thought deep silver made it. I read adding the registry might work, but not to do it if we're not comfortable with that, and I don't trust myself editing my laptop's registry.Is there anything else I can do?
