Removing a License from a VE License Server

Sometimes, it may be necessary to remove a license from a VE License Server.

Important note:

• Once a license has been installed on a license server, the license id will remain the same until the operating system of the license server host is reinstalled, or the license is transferred away from the system.
• Reinstalling the license server software (RPM) and/or deleting the directory /opt/license-server (VE versions before 2.4.9) or /opt/charon-license-server (VE version 2.4.9 or later) will stop the system from being a license server, but not remove the original license id.
• After reinstalling the license server software (RPM), only the original license (V2C with the same license ID) can be installed to restore the former license server state.
• Any C2V file created without first completely removing the license (see below) will contain the original license ID making it impossible for Stromasys to create a new license.

Completely removing a license from a VE license server system:

This step is necessary in the following cases:

• Cleanly erasing the license from the current license server system for any reason.
• Transferring the license to a different system.
• Preparing the current system for the installation of a completely new license (for example, changed fingerprint or new license owner). In this case, the transfer must be done before creating the new C2V file.

For such cases, you must use the C2V transfer option: c2v -t <filename>

Please note:

• VE versions before 2.4.9:
  • The transfer option cannot remove invalid licenses (e.g., expired or license with broken data). In such a case, perform the following steps:
    • Backup the file /opt/license-server/stromasys-logo.bmp.
    • Uninstall the older VE license server software.
    • Install version VE license server version 2.4.9 or higher.
    • Replace the file /opt/charon-license-server/stromasys-logo.bmp with backup of the old file.
    • Perform the transfer operation to remove the invalid license.
    • Restore any additional customization (e.g., config.ini, non-default certificates, AutoVE instances.db).
• VE version 2.4.9 or later:
  • The transfer option can remove also invalid licenses.
• A transfer can only be executed on the original system only once. A second attempt will produce an error message since the license has been removed by the first transfer.
• Once a license has been transferred out from a license server, it can only be installed again on the same system if the transfer file is sent to Stromasys together with a new C2V from the system.
