Licence number is not able to unlock the product

I agree that this is a nuisance, but there are some design reasons for it. The license manager can only check the overall correctness of the license, but the product itself checks its validity.

From inside the application it is possible to examine the LicenseInfo on the EasyXXlient object. There is a "SerialNumber" entry - it either has your own serial number, or 1111111120 if the trial license is in effect.

Best regards

Your license has been bought with a maintenance period of 1 year, and covers all versions released by May 15, 2016.

The current version (5.40) has been released in June 2016 and is therefore not covered by your license.

You need to either stick with 5.3x versions, or purchase a version upgrade.

Best regards
