In some emulator products it is possible to configure the number of retries and the waiting time between them by adding parameters to the emulator configuration file. Please refer to the product documentation for the details regarding the relevant parameters: license_retry_period and license_retry_count parameters (obsolete starting with version 1.10)
2. At regular intervals during the runtime of the emulator (the default license check period of 1 hour can be changed by Stromasys using the appropriate license parameters):

A software license does not require any special hardware but it still requires installation of the Sentinel runtime environment.
Please note:
- To avoid unexpected problems, do not use any Sentinel runtime software that was not provided by Stromasys without being advised to do so by your Stromasys representative.
- Software licenses are best suited for stable environments, because their correct function depends on certain characteristics of the host system. Changing any of these characteristics will invalidate the license.
- If the Charon host runs on real hardware, software licenses are by default tightly bound to the hardware for which they were issued. If major hardware characteristics of the system are changed, the license will be disabled.
- If the Charon host runs in a virtual environment (e.g., VMware), software licenses are normally bound to the virtual machine ID and a set of additional characteristics of the virtual machine. If any of these parameters are changed, the license will be disabled.
- Software licenses are very sensitive to even small changes on the host system. Therefore, it is especially important to provide for a backup license that will ensure continued operation should there be a problem with the software license. See Handling Multiple License Keys and Product Licenses for details.

Use ssh to log in on the license server instance.
# ssh -i ~/.ssh/<mykey> <user>@<license-server-ip>
where<mykey> is the private key of the key-pair you associated with your cloud instance
(for an on-premises VMware installation where login with username/password is allowed, it is not needed)<user> is the user for interactive login associated with your license server instance (e.g., opc on OCI, centos for a CentOS instance on AWS, or the custom user on your VMware virtual machine or physical server; for an instance installed from a prepackaged Charon VE marketplace image, use sshuser centos)
<license-server-ip> is the ip address of your license server system
Become the privileged user and run the c2v program.
Become the root user: # sudo -i
Run the c2v program: # /opt/license-server/c2v --filename <my-file>.c2v --platform <my-platform>
where<my-file>.c2v is the path and name under which you want to store the fingerprint. The file type is C2V (customer-to-vendor)
<my-platform> indicates the platform on which the license server runs (possible values: physical, aws, oci, gcp, azure, ibm, nutanix, or esxi).
Copy the resulting C2V file to your local system (unless you can send email from the license server system).

Copy the V2C file to the license server (e.g., with SFTP).
Use ssh to log in on the license server instance.

<license-server-ip> is the ip address of your license server system
Become the privileged user and run the v2c program.
Become the root user: # sudo -i
Run the v2c program: # /opt/license-server/v2c -f <my-file>.v2c
