Diablo 3 updating
The game requires it and will not run if it's disabled. f you're encountering crashing when launching the game, we ask you to check and see if you have any of the following third party programs running.To check, open Control Panel Services and scroll down to the Secondary Logon service. • Mumble • XFire • EVGA Precision • Airfoil by Rogue Amoeba • MSI Afterburner • Dxtory • Radeon Pro • Taksi In some cases, simply updating the program can resolve the issue, but if it continues, we suggest not running these programs at all while launching Diablo III.
If you have the game downloaded to D:\Games\Diablo-III-8370-en GB-Installer, please point the download to D:\Games\.
As has been mentioned, launching the Diablo 3 downloader and directing it to the same folder as before will allow it to download the installer files again.
Please make sure to leave the downloader alone as it works.
In almost all cases it has to do with an overlay that the 3rd party programs use that causes the crash.
If you participated in the Diablo III beta, we recommend removing all Installation Files before attempting to install the retail client.
