The "most awesome launch night ever" has quickly turned into "the worst possible launch night of any game ever" with this. At least on other launch nights, I could install the damn installer.

I'm having the same problem too. I was able to get to the installation screen two month ago and when I clicked install I would get the message that says the game hasn't launched yet.

And just today, I encountered the same situation as I read through all posts:

downloader getting stuck at 1/3
deleting files in ProgramData
secondary logon
sutting down Agent in task manager
"Updating data files..." goes up to 2/3, 95%, then back down to 2/3 and stops
getting critical error on Agent
pulling my hair out
wiping tears

Still looking for blue help.

God help us all.

The quickest way for Blizzard to fix this would be to discontinue using the new battle.net agent and go back to 'tried and true' methods.

Yeah now installed new SP1 for WIN7 and BAM. Back to the old fn problem with agent.exe collapsing, while everything toward beta files / programdata is deleted. Everything gone, reboots done nothing helps.

what i found worked for me with the "Updating setup files..." issue was i downloaded the battle.net folders from


because im running windows XP 64 bit edition, i went to C:\>Documents and Settings>All Users>Application Data and i replace the battle.net folder in there with the downloaded one, ALSO in the Application Data folder, there is a Blizzard Entertainment folder, i had to replace the Battle.net folder inside both the Application data folder, and the Blizzard Entertainment folder. after that i just ran the Diablo-III-Setup-enUS and it got past the "Updating setup files..." issue very quickly.

Just downloading the game now and good to go :D

Hopefully this helps!

Ok guys. Now I am first time on the road to actually install this damn game.

Done parts:

Deleted all the progra shiet which explained before

regedit.exe -> killed all agent.exe things and all battle.net roots

-> killed agent.exe from system manager. Now everything is clean -> hit install from .exe.

Now going 15% !!!

Here's some steps I found from a user on the MOP Beta forum. It's worth a try as they have the same issue with Agent.

STEP 1: open your internet explorer and do the following:

internet options > Connections > LAN Settings > uncheck "Automatically detect settings"

STEP 2: CTRL ALT DEL Kill any Agent*32/Launcher.exe

go to : C:\ProgramData\ and delete the Battle.net folder (THE WHOLE FOLDER)

Run the installer now. When it seems to hang:

Start Task Manager and end the Agent.exe process (not process tree). Then take a look at your updater. It should complete.

Support Information Administrator

I tried this and it hasn't helped. Thankyou for the work you are putting in but seriously who created this crappy installer

I feel so stupid because im a WoW anual pass holder, so i had a free d3 to begin with, but at midnight when the game droped i went and bought a retail copy in hopes that it would fix that problem >< what a terrible 67$ mistake that was but really we shouldnt have had any issues to begin with, they held the game off for so long they could have held it off a little more to make the installer work properly

Hi all,

I resolved this issue by doing the following

- start secondary logon service and set to automatic
- delete battle.net folder in the program data folder
- run launcher as admin
>>> At this point the 'updating setup files' froze at about 95% <<<
- let it sit there for a couple mins and then opened task manager and killed the Agent process, did not kill the D3 setup process
- The agent service did not restart as it normally would, i went to C:\ProgramData\Battle.net\Agent\Agent.954 and ran agent.exe as admin
>>> The progress bar then went back to halfway, and then started processing all the way to 100%<<<

i am now installing the game.

Okay, I think I just got lucky. It finally installed for me, and now I'm busy installing the game from the launcher.

Yeah, I had to wait for about 30 minutes for it to finish from the last agent reset (where I essentially just ended the Agent 32 process) for it to install, but I doubt it was patience that prevailed rather than just the combination of everything I have done tonight.

All in all -
about 15 battle.net deletes
about 4646546546 agent resets
about 27 restarted updaters
half way in compatibility mode: XP SP3 and half in compatibility mode Windows 7
987654321654 frustrated posts

Note: none of these are hyperbole. I actually took the time to count everything. And if you believe that, I'm also a billionaire who will buy Activision, fire Bobby Koteck, punch Mr. Morheim (in the face with that dwarven accent), and install 2345628374562093475290375243908572390487 more D3 servers. And if you still believe all of that, then the only thing I require from you is all of your collective firstborns.

my bet is blizz has done this deliberately to delay everyone playing at the same time
and then when the updater works theyll come up with some lame excuse

Ok so I checked the Secondary logon, it was set to manual already, but I switched it to Auto to see if that worked. No dice. Now i'm trying to delete the Battle.net folder, and my computer is telling me that the action cannot be completed because a file in it is open in another program, but I don't have anything open aside from iTunes and this webpage... Any other thoughts?

EDIT: Ok, so downloaded file posted in thread as it seemed to work for so many people. Ensured my Blizzard folder was deleted and Cache folder. Ran as admin, got to 1/3 as per usual. Task Manager > Ended agent.exe file and launcher continued up to about 95% then changed from "Updating Setup Files" to "Loading Blizzard Launcher". Yay! But no... agent.exe reappeared and launcher went back to "Updating Setup Files" and 2/3 progress bar and stuck... Don't know what else to do. :/

My Fix as follows.

Downloaded the battle net files linked in the thread
Put them in the corresponding folder.

No agent.exe running.
Using the CD from the store (bought gf a copy...so i could use the CD).
ran regedit.exe

-searched the registry for agent.exe, found the first one and deleted it that was actually linked to the bnet folder, don't remember the location, went through a few more and deleted a second which was in the firewall rules section, probably didn't need to delete that.

ran the client setup in the battlenet folders downloaded, got the installer instantly (run as admin) however couldn't install as decompression error occurred (due to no downloaded files no doubt).

So i then closed everything, and ran the setup from the CD (which is in a folder on the PC, no cd drive so copied it through lan to mine from gf's pc) no iso etc, just folder with contents dumped in it.

Win 7 x64.
windows firewall off
selective startup.

Secondary login i changed awhile back to allow desktop to use it or something, tickbox in config somewhere, also changed it so that on 3rd fail it would just try to run it again instead of stopping the service. (no idea if that is relevant, as it was the bnet files that seemed to really change anything for me).

Done all from a tethered Iphone, so wasn't able to test safe mode stuff.

Hope this helps somewhat.

using the new nvidia 680Gtx, standard drivers from release date.
that's about all i can think of that's relevant, cheers.
