Dungeon Defenders won't start

My friend is having problems, whenever he launches the game, it just crashes. No error messages, nothing, it just closes.

He's tried disabling firewalls, lowering settings, starting in windowed mode, updating his graphics card, reinstalling, changing his locale setting to the UK and vertifying the integrity of the cache.

Whats the problem??? Thanks!

Thread moved.

Maybe a steam issue itself? Try to remove *.blob files inside of the Steam folder, where you will find steam.exe

:)

Any of these may help him:

Q:From the Dungeon Defenders Launcher I press play and the game crashes. Or game doesn't launch at all.

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

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.

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.

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 . NOD32 should be okay with DD now since NOD32 fixed the false positive but if NOD32 is still flagging the program make sure your NOD32 definitions are up to date.
