So I've got the same issue as many other people of during the installation it sends an error while trying to copy a file. The source file is corrupted. I have downloaded the whole game, even tried turning off my anti-virus which did nothing. If it helps, the file that it is struggling to download is Ironsight/data/map_tower.wpg . I have been looking forward to playing this game so please help ASAP.
Before sending this, I looked around the forums and noticed a lot of other people having the same problems and then getting a direct message from Heiliger on how to fix it so if possible, I would appreciate that. Thanks
