For Windows user running a 64 bit version of the system. If you feel adventurous you can try downloading the 32 bit version of the game with SteamCMD and check if that runs any different.

1. Download SteamCMD here: [http://media.steampowered.com/installer/steamcmd.zip]
1. Extract to any folder
1. Run ''steamcmd.exe''
1. Type (do not include the brackets for the username/password):
{{{
login <youruser> <yourpass>
@sSteamCmdForcePlatformBitness 32
force_install_dir ./7dtd/
app_update 251570
}}}
1. Check if the program gave any errors during the download process. If not type ''exit'' to close it.

This will download the 32 bit version to a subfolder "7dtd" in the SteamCMD folder. You can start the game from there manually now.


If that helps for a problem you have with the 64 bit version please report that, including what your problem with the 64 bit build was.
