The second scenario involves an empty USB dongle (containing only the serial number but no license data) and a separate license file provided on CD-ROM or via electronic download. This configuration requires manual activation of the license file through the Chromeleon Administration Console.

Yes, but USB passthrough for the dongle must be supported by your virtualization platform (e.g., VMware, Hyper‑V). The license file itself does not care about virtualization, but the dongle must be physically attached to a host USB port and passed through to the guest VM. chromeleon license file

Verify that the counts for (e.g., Class 1, Class 2 instruments) match your purchase order. Click Apply and then OK to commit the changes. Troubleshooting Common Chromeleon License Issues

There are many scenarios where you may need to transfer your Chromeleon license to new hardware: upgrading an instrument PC, replacing a failed computer, or re‑deploying equipment within your laboratory. To avoid unexpected lab downtime, incorporate these habits

If an IT technician replaces a motherboard or network interface card (NIC) on a chromatography workstation, note that it will break the license. Plan the license rehost ahead of time.

The License Server installation typically occurs during the Chromeleon setup process when the appropriate option is selected. During installation, you will be prompted to provide a license file—specifically the file that contains the server's licensing information. This INI file defines which hardware protection modules are authorized, which clients can access the server, and what network protocols to use. The license file itself does not care about

If your lab is subject to FDA 21 CFR Part 11 or EU Annex 11, the license file is a "System Configuration Record." Mismanagement can lead to audit findings.

Designed for standalone computers physically connected to chromatography instruments. The license file resides directly on the local PC and activates features only for that specific machine. Network (Enterprise) Licenses

The activation process depends on your license type and when you perform the installation.
