This Information Applies To: Agilent OpenLab ChemStation Edition Software (C.01.xx)
Issue
When your Agilent OpenLab ChemStation Edition software fails to launch with errors "Login failed with the following message: Configuration system failed to initialize. ChemStation will shutdown now", this article will provide you some basic steps in troubleshooting the issue.
Background
This error message is usually the result of a corruption in the user.config file or a corrupted instrument configuration (typically stemming from an unexpected shutdown or power outage).
Resolution
Rename or delete the file. It will be recreated automatically during the next ChemStation launch process.

- Close all OpenLab ChemStation software app.
- Rename or delete the user.config file; it can be found at the following location:
- Windows 7/ Windows 10 PC: c:\users\<logged on user>\appdata\local\agilent_technologies\chemmain.exe_url_xyz\2.0.0.0\user.config
- Windows XP PC: C:\Documents and Settings\<logged_on_user>\Local Settings\Application Data\Agilent_Technologies\CHEMMAIN.EXE_Url_xlvsr1c1b5wijktns4g1gcbrae3dl030\2.0.0.0\user.config
- On AIC (Agilent Instrument Controller): C:\Users\username\appdata\local/Agilent Technologies\ChemMain.exe_url_xyz….\’2.0.0.0\user.config
- Reboot the computer.
- Launch the online session.

Corrupted instrument configuration
Rename or delete the RapidControl.InstrumentConfig.xml file. It will be recreated automatically during the next ChemStation launch process.
- Close all OpenLab ChemStation software app.
- Rename or delete the RapidControl.InstrumentConfig.xml file; which can be found at the following location:
- Windows 10 PC: C:\ProgramData\Agilent Technologies\Chemstation\# (where # is the instrument number)
- Windows XP/ Windows 7 PC: C:\Chem32\# (where # is the instrument number)
- Windows 10 PC: C:\ProgramData\Agilent Technologies\Chemstation\# (where # is the instrument number)
- Reboot the computer.
- Launch the online session.
- If it does not work, create a new instrument (see How to Configure an HPLC Instrument in the Agilent OpenLab Control Panel Using Auto Configuration or How to Add a GC Instrument in Agilent OpenLab CDS (Ver 2.x) ).
In case deleting the user.config and RapidControl.InstrumentConfig.xml files do not solve the issue, create a Windows user profile and try launching the instrument.
If the issue continues or further help is required, contact your local Agilent Support.
