Cannot launch D4 at all

I’ve been having this problem pretty much any evening I try to play D4 since it went live. I had zero problems during pre-release, but now that the game has launched, I pretty much can’t even start the game during the evening. I launch battle.net, click on “Play” for D4, and the play button changes to “Loading”. Then about 30s to a minute later, it just goes back to “Play”. No error codes, no messages, no loading or launch screen. Nothing.

I just rebooted my PC, I’m running the 1.0.4 update (version 1.0.4.42942), and I restarted battle.net after installing the update. Some kind of error message or feedback would be nice, but this is just really frustrating. What can I do to fix it?

I just bought the game and I am having the same issue. Haven’t been able to get it to launch even once.

Two things to try:

Since you played in beta I would do this first…

  • Close Bnet app, make sure its shut down.
  • Open Documents\Diablo IV folder.
  • Delete the LocalPrefs file located here.
  • Restart the bnet app. Try to play again.

Then if that doesn’t work:

  • Check to see if the bnet app is running in compatibility mode.
  • Right-click the bnet shortcut.
  • Go to “Properties”.
  • Under here look for the Compatibility tab.
  • Make sure that its not set to run in Compatibility mode.

You will need to exit and restart the bnet app after making that change.

Next if those don’t help, download the latest driver for your video card from the chipset manufacturer. AMD or Nvidia or Intel. If they have an option to clear old driver settings during installation (for example, Nvidia has a clean install option) then do that as well. It will reset the driver defaults.

See if those things help at all.

Ya neither worked. The only thing I can say that is weird is that it wouldn’t let me launch it initially because my gpu driver was out of date. I updated it and I can run any other game except this one. I put in a ticket so I guess if they can’t solve it I’ll just refund. Sad day.

Can we get some PC specs?

Ok I figured it out. For some reason my laptop was forcing it to use the onboard graphics instead of dedicated. I went into graphics settings and changed it to only use the dedicated gpu. That worked!

UPDATE: I decided to try rolling back my Geforce video card drivers. I did a Clean install of geforce experience and driver 536.23 . Now I am able to play the game. The newer version 536.40 is (I think) what broke it.

ORIGINAL:
I am having the same issue. I played the Betas without a problem. I had been playing on the weekends without a problem, but last Friday 6/30, the game crashed. I tried to reopen it and it would not open. Then I was getting an “Out of Memory” Error, saying that Diablo IV has run out of memory. I did some windows diagnostics, and found out there was an issue with my RAM. I’ve since upgraded my PC with a new motherboard, RAM, etc. I did a clean windows Reset and reinstalled Battlenet and Diablo IV. It still won’t open. All drivers are up to date. I hit play and it acts like it will start but the button reverts to Play again. Sometimes I get a gray screen that opens/closes and once in a while I still get the memory error, although I know memory is not an issue. It is not running in compatibility mode. I deleted the LocalPref file. I’ve gone into my windows and graphics to make sure they are set to my graphics card and not the onboard. I don’t know what to do. This is the only game I have that will not play.
