How can I activate a software license?


To run the software license, the authorization file AUTHOR.INI is required, which contains the product key information. If there is no valid license found when starting the program for the first time, the Authorization dialog box appears.

Select the Use full version option and click the [OK] button. A Windows dialog box appears, where you set the path to the AUTHOR.INI file and confirm by clicking the [Open] button. Make sure that you are connected to the Internet.

As soon as the authorization is loaded successfully, the following message is displayed: Authorization completed successfully.
