I have been seeing reports that players are having issues running Diablo III by clicking the game client's icon in the Diablo III folder, and after having experienced the same by testing on my installation, I have determined the cause and found a series of steps that will resolve this issue for you and allow you to once again use the Diablo III icon to launch your game as you did prior to this patch:1) Navigate to the folder containing the Diablo 3 game executable and the Diablo 3 Launcher.2) Delete the file Diablo III Launcher (move to trash via CMD-Delete/Backspace).3) Run the Blizzard Desktop App.
You should already have this as it is required to run Diablo 3 as of 2.0.1.
The issue should now be resolved regarding the Diablo 3 app failing to run the Launcher.
It seems that the initial patching download from the CDN servers had a corrupt file (the launcher) which appears fixed as of today and deleting and redownloading it resolves this. :)________________________________________________Technical Support MVPThank you will def try tonight...
As thousands struggle to play Diablo 3 and servers buckle under the strain, Blizzard has explained the various error messages players are receiving as they attempt to log-in - and offered advice on how to deal with them.
Two of the more popular error messages are 37 and 12.
Solution 1 – Make sure that your drivers are up to date Diablo 3 crashes can be caused by outdated video driver, therefore if you’re experiencing any issues with Diablo 3, we strongly urge you to update your drivers first.
Many users reported that downloading the latest drivers for their graphic card fixed the crashing issues, so make sure you try that.After a reasonable hiatus from Blizzard games, I have decided to reinstall Diablo 3.I used to have it installed and working on this machine and removed my previous install using Add/Remove Programs.However, now when I try to reinstall the game, the Diablo 3 Setup starts 'Updating setup files...' and then hangs; I have had a quick google for ideas on how to fix it which seems to bring up a bunch of posts when the server loads were really high last year, nevertheless I have been through the list of suggestions, making sure that secondary login is enabled, running the installer as administrator, etc.After leaving the installer for ~30 minutes, it finally brings up an error stating it could not run the Blizzard agent; This gives me an error code - BLZPTS00007 - which gives me a few more google hits including a seemingly official guide on how to troubleshoot agent issues on Battle.net, however performing the steps listed under 'Advanced Troubleshooting' still hasn't resolved my problem.We'll keep this post updated throughout the next couple of days with the latest problems and info on how to fix them.
