This Information Applies To: Agilent OpenLab ChemStation, Agilent OpenLab CDS, Agilent OpenLab EZChrom
Due to the license error “An error occurred connecting to the license server: The desired vendor daemon is down. Check the Imgrd log file, or try Imread. Feature", it is not possible to launch the instrument session.
Close all Agilent OpenLab software applications and log in to the PC as an administrator.
After some events, especially if Windows was shut down abruptly, for example, a power supply failure, Agilent software cannot be launched due to license error. These errors can be caused by services or vendor daemon not started, corrupted files, or by the "lmgrd.exe" process.
Another error message examples:
Solution 1: Ensure that the name of the computer was not changed. If the name is different, either:
Solution 2: Stop and restart the Agilent OpenLab Services (see How to Restart Agilent OpenLab Services in Windows 10).
Solution 3: Delete or rename activation_state.xml and/or concurrent_state.xml:
concurrent_state.xml.old (Figure 1).
Solution 4: Retrieve a new license file (see How to Return and Update a License File for Agilent OpenLab Software).
Solution 5: There is a process called Lmgrd.exe, which is not installed by Agilent through the OpenLab master installer. This file monitors the FlexNET Publisher and prevents it from recognizing the licensing as valid. Since this process is not an Agilent feature, consult with the IT department about the Lmgrd.exe process to avoid conflicts with other software installed in the PC.
