Solution or Workaround

The following solutions have been found to work with the greatest frequency.

  • Log into the computer as the administrator and test ArcToolbox. If it starts ensure the user account has at least Read/Write and Execute permissions to the $ArcGIS\bin directory and TEMP.
  • Perform a clean reinstallation of the ArcGIS Desktop software.
  • Reboot in Safe Mode and start ArcToolbox. If it opens, there is likely a conflict between Toolbox and a service running on the computer. The most common conflict to date is a piece of software called PrintLog, made by a company called Equitrac. Uninstall the PrintLog and test ArcToolbox.
