Agent.Exe Crash during Install / Updates FIX

Posts: 20
    To solve this error on my windows 7 64-bit install I performed the following steps:

  • Click Start
  • RUN "msconfig"
  • Under the General tab, click Diagnostic Startup
  • Click OK
  • Restart the PC
  • Upon restart, delete the folder in "C:\ProgramData" named "Battle.net"
  • Right click on the launcher and select "Run as administrator"
    • Note: You can add the step to remove security and anti virus but it did not matter in my case.


    You should not recieve any errors this go around. For myself, I had uninstalled every uneeded program including AVG. I had also disabled windows firewall. Finally I first tried to run the install with only stopping non microsoft services, however, that failed and resulted in the dreaded agent.exe crash. The fact that it worked when I went to diagnostic indicates that there is a service (possibly specific to w7 64bit) that is interfering with installs and updates.

    I'll be re-enabling them until I find out which one it was... Until then, good luck and happy slaying!

    OR
    just go in the folder and click on the agent updater. then itll update and work again. I posted this fix like 2 days ago
    C:\ProgramData\Battle.net\Agent
    Remember that program data is a hidden folder. Inside Agent there are a couple more folders that say Agent. i clicked on the .954 agent folder and used that updater. There is another updater in the other folder.
    Im unsure on the difference. All i know is it fixed it

    None of those fixes work for me. Even tried them in safe mode with networking enabled. I just keep getting a Windows error message saying the Agent setup has stopped working, after which all I can do is close it. When ran in safe mode with networking, I don't get the windows error but it will just keep looping the setup.

    You are probably not going to like this, but after 2 solid days of this error & failure to install, i backed up my data, pulled out the XP disk and wiped my system. The new system is up and Diablo 3 is working perfectly.
