Finding the Version and License or Serial Number – TEKLYNX Label Software Instructions


Instructions on how to find the serial number for an existing instance of TEKLYNX software running on a PC.  This applies to  instances that either are currently activated or have been activated in the past (and perhaps expired). This includes:


IMPORTANT NOTE: Demo instances TEKLYNX software never activated do not have a license or serial number.  Attempting to run an instance of the TEKLYNX software or run the TEKLYNX License Manager on a computer that has never had an activation installed will yield an activation screen (i.e. no License #).

Generally, the license / serial number can be found either:

  1. Using the Help / About screen once the application is open
  2. Opening the License Manager application (typically installed with the application on the PC)

1. Using the Help / About Screen

Open the application, select Help then About

The screens look slightly different based on the version and brand of TEKLYNX software (CODESOFT and SENTINEL shown below as an example):

  2. Softkey Activation
