What do I do if my Aspen Online interface doesn’t open?


Solution
If customer is having problems opening the Aspen Online Graphical User Interface (GUI), first review the services list to see if the service “Aspen OnLine V11.0” is running.
Possible reasons for AOL service not running:
  • Service startup type is set to Manual
  • Service is set to Automatic, but the system is slow and service did not start up during reboot (set it to Automatic Delayed)
  • Incorrect/expired password for the log on account
  • SQL Express 2014 service not running (if using Local System account)
  • Instance not selected (if using Local System account)
    • Use “select instance” batch file (found under C:\Program Files\Aspen Online V11.0\)

If the service is running but GUI still can’t launch:
  • AOL Service appears to be running, but it didn’t connect to SQL or localdb or SQL Express successfully
  • Hanging AOL processes – stop service, kill process, start service again before restarting GUI
  • Look for log files in C:\ProgramData\AspenTech\ AspenOnLineV11.0\system
