Delete license files

Dec 14, 2016

When you upgrade your edition (for example, Advanced to Enterprise, or Enterprise to Platinum) you receive new Citrix product licenses that you can allocate to one or many Citrix License Servers through license files created at Rescinded licenses must be removed from license servers within ninety (90) days of new license purchase. Removing the licenses enables:

  • License asset management
  • License compliance
  • Remove unnecessary alerts from appearing in the management console
Considerations when deleting files:
  • Incorrect removal of license files could inadvertently lower the total licenses available.
  • Place any new license files on the license server prior to deleting any licenses.
  • Remove a license file only when all INCREMENT lines in the file are obsolete or unnecessary. For example, every increment line has been replaced with a new license as a result of an upgrade.
  • If you used the License Administration Console to add license files, you have to update the console UI for any deleted files.


Never delete the options file (citrix.opt) or startup license (citrix_startup.lic).

  1. At the license server, open the Services panel and stop the Citrix Licensing service.
  2. Open Windows Explorer and navigate to where the license files are stored. By default license files are stored in:
    • C :\Program Files\Citrix\Licensing\MyFiles on a 32-bit server
    • C:\Program Files(x86)\Citrix\Licensing\MyFiles on a 64-bit server
    • /opt/citrix/licensing/myfiles for License Server VPX
  3. Back up all license (.lic) files.
  4. Using a text editor (Microsoft WordPad is recommended), open each license (.lic) file and identify the obsolete license feature INCREMENT line(s).
  5. Ensure all increment lines are obsolete or unnecessary. See License file format for information about increment lines.
  6. Close the file and change the file extension from .lic to .old.
  7. In the Services panel, restart the Citrix Licensing service.

To update the License Administration Console UI

If you added license files with the console, you must update the console UI after removing those files.

  1. Start the console and click Administration.
  2. Log on as an administrative user and click the Vendor Daemon Configuration tab.
  3. Select the Citrix vendor daemon from the list.
  4. Edit the contents of License File or Directory to remove any deleted licenses and then save the configuration.
