Troubleshooting BOINC

Problems installing BOINC

(Windows) In rare cases, installation may fail because of an existing installation of BOINC. If this happens:

  • Quit BOINC if it's running, and uninstall BOINC using Start/Control? Panel/Add? and remove programs. Install the new version again.
  • If that fails, reinstall the version of BOINC you were previously running (old versions can be found here). Uninstall it as above, then install the new version.
  • If that fails, download the Windows Install Clean Up utility from Microsoft and run it. The old BOINC version shows up as either BOINC.msi or as a corrupt icon .msi (it'll be the top option). Click on it to select, then click Remove and Exit. Reboot your computer. Install the new version. (Warning: leave all other .msi files as they are, otherwise you will have problems uninstalling other programs).

Problems attaching to a project

If you try to attach to a project that's down, you'll get a Project temporarily unavailable error. Wait a while, then try again.

If you get a Network communication failure, it means BOINC can't do any communication at all. The likely problems are:

  • Connectivity: you don't have a network connection. Check your network or modem connection (if your web browser can get to outside sites, this is not the problem). Info on Windows networking troubleshooting is here.
  • Personal firewall software (ZoneAlarm, Norton Personal Firewall, McAfee, etc.) is blocking BOINC.
    • The first time you run BOINC, your personal firewall will bring up a dialog asking if boincmgr.exe and boinc.exe should be allowed to communicate (say yes).
    • If this dialog doesn't appear, bring up your personal firewall program and add an 'exception' entry allowing BOINC to communicate. If it already has an entry for BOINC, delete it. Detail vary between firewall packages.
    • You may have accidentally installed more than one firewall. Uninstall or disable all but the primary one.
  • Proxy server: there are two kinds of proxies, HTTP and SOCKS. You may be using one or both. Most home computers do not use proxies. To find out if you're using a proxy, look at the Internet settings of your web browser. (Firefox: Tools/Options/General/Connection? Settings; Internet Explorer: Tools/Internet? Options/Connections/Settings?). Copy the settings there (server, port, etc.) to the BOINC dialog.
  • (Windows) SETI@home: if it appears to attach OK, but the Messages tab has repeated shared memory error messages from the server: uninstall BOINC and delete the install directory (typically C:/Program Files/BOINC). Reinstall BOINC, but in a different directory (such as C:/Program Files/BOINC2).

Problems while running BOINC

  • (Windows) If screensaver graphics aren't working, make sure you have the latest driver for your graphics adapter.
  • (Windows) If BOINC applications are repeatedly crashing on your computer, it's possibly that you need to upgrade to the latest version (9.0c or later) of DirectX.
  • (Windows) If you repeatedly see

Can't delete previous state file; Access is denied.

in your message log, you're probably running a program that is accessing files and keeping them locked for long periods. Try using Microsoft's FileMon utility to discover what the offending program is, then configure it to not access files in the BOINC directory. Known problems: TSVNCache (part of TortoiseSVN).

  • (Windows Vista) If BOINC applications fail each time you shut down your computer, copy the following text and paste it into the Notepad window, called WaitToKill.reg:
      Windows Registry Editor Version 5.00

      [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl]
      "WaitToKillServiceTimeout"="20000"

The 20000 is 20 seconds. Increase/decrease to your liking. To add this to the registry double-click the file. The UAC will come up, press continue, press Yes on the next window and OK on the one thereafter. You need to reboot to make the changes have effect.

  • (Linux): if the web site buttons in the Manager don't work, make sure your $BROWSER environment variable is set.
  • If you have a problem with a particular project, go to the 'Questions and Answers' area of the project's web site. You may find the solution to your problem. If not, post it there, and you'll get help from other users. If the problem persists, use the BOINC Manager to 'reset' that project. This will erase any jobs in progress and start from scratch.
