I have the box version and i just installed it but can't download 1.02 patch, it keeps saying "download failed" and tries to download again with same results. So i decided to also download the "pre-download" version form GOG Galaxy and see what will happen. Also the patch from the link does not work for me, i cannot install it manually either.
@Update: Problem solved! It was my damn Antivirus! I deactivated my AV and updates where installed just fine!
^ works. Damn Avast. Always trying to ruin our fun
