you can find the list here.
#5 worked for me, where i downloaded a copy of the setup files and extracted the zip file on
which should contain "C:\ProgramData\Battle.net"
the folder should have 3 folders inside:
Agent, Client, Setup. (where Client is the one that got stuck during the Agent launcher).
If you can't find the folder above, then it's because ProgramData is hidden. please just do yourself a favor and search for how to "Show hidden folders in <OS>".
After i got through this, i encountered the error when Diablo III installation started. it only went up to 0% and prompted this:
"C:\Program Files (x86)\DiabloIII.temp". (ConflictManager:CreateObjects)
And this might mean that the user doesnt have permission to write in the program files folder. which got me puzzled since im an Administrator, and i just installed my OS.
And it's Windows 7 Ultimate 64 bit
I had no choice but to reinstall my OS again! using Windows 7 Ultimate (the 32 bit Version!)
and i crossed my fingers and spent hours again without sleep to wait for installation.. blah blah..
And then finally, i did Diablo 3 installation again from the start (same error as the initial part) and then got to the launcher part, where it went from 1% to 69% (and i again encountered another "stuck in oblivion" where the percentage wasnt moving)..
turns out, it was just the Internet Options.
go to your internet explorer > (Menu) Tools > Internet Options > Connections (tab) >
click LAN Settings (below) > uncheck "Automatically Detect Settings" > OK.
you can do the last set of steps above even during 69% or 77%. and then you will see that in a few minutes it will continue downloading.
And after 10 hours of installation.. hope you share this info if it helps you.
