Finding the Version and License or Serial Number for a SENTINEL License – SENTINEL Instruction Article
Summary
Instructions on how to find the serial number for an existing instance of SENTINEL running on a server. This applies to SENTINEL instances that either are currently activated or have been activated in the past (and perhaps expired). Demo instances of SENTINEL that have not been activated do not have a license or serial number. Attempting to run an instance of SENTINEL or run the SENTINEL License Manager on a computer that has never had an activation installed will yield an activation screen (i.e. no License #).

Instructions
Generally, the license / serial number can be found either:
- Using the Help / About screen once the application is open
- Opening the License Manager application (typically installed with the application on the server)
The Serial Number box contains the software serial number. It should look something like this: MKH72444 or NSPF66236.
1. Using the Help / About Screen
Open the application, select Help then About

The screens looks slightly different based on the version of CODESOFT:
The splash screen should have the license number listed as “S/N” or “Serial Number”. Typical format is 3-4 letters followed by 5-6 digits (e.g. MKH65893, NSPF108919, etc.)
2. Opening the License Manager
Running the SENTINEL License Manager will yield different screen depending on activation type:
- USB Hardkey Activation
- Softkey Activation
