Q:From the Dungeon Defenders Launcher I press play and the game crashes. Or game doesn't launch at all.
A:
Possible Fixes:
Please make sure your in-game resolution is the same as your desktop resolution.
If you have GamerOSD, please uninstall this and try launching.
File Re-Name:
C:\Program Files (x86)\Steam\steamapps\common\dungeon defenders\Binaries\Win32
Rename DungeonDefenders.exe to DungeonDefenders.old
Then rename DunDefGame.exe to DungeonDefenders.exe
DunDefConfig.exe:
Some people have been able to run DunDef through their exe file, WITH STEAM CLOSED
File Path-
c:\steam\steamapps\common\dundef\Binaries and start DunDefConfig.exe
Then you should be able to "Launch" through that window
Region Setting:
If your PC is set to any Locale outside of English, German, French, Spanish, and Italian, try changing your Locale to one of these. You can follow these general steps to do this:
Control Panel > Region and Language > Administrative > Change System Locale
We are working on a fix for this ASAP.
Anti-Virus Program:
If you are having issues launching, did you have an Anti-Virus program running at the time you downloaded the game? It could be blocking some files from being downloaded. Try disabling your Anti-Virus program and re-downloading everything and see if that works.
Verifying Cache:
1: Open your steam library
2: Rightclick the game (

(Thanks to zoomg for the pics.)
Deleting Local Content:
Go into your Program Files and follow the path:
Steam > steamapps > Common > dungeon defenders > Engine
Delete the folder "Localization"
Perform a reinstall.
Move Your Steam Folder:
If you had Steam installed on the Program Files (X86) folder or on a different drive entirely, please move it to your root C: drive (the folder which contains the Program Files folders).

I moved the whole steam folder to another location and it worked. (c:/games/).
If you have AVG or Panda Cloud Anti-Virus:
Try uninstalling it and see what happens.
If you have NOD32 installed make sure it did not remove DunDefGame.exe from C:\Program Files (x86)\Steam\steamapps\common\dungeon defenders\Binaries\Win32 .
