May I know if anyone has the successful case that has been successfully applied with the license key eg Dashboard or Chartpro or Elastic Report with long computer code generated?
The long computer code may be related to the number of network interfaces, if you use Virtualbox or similar programs and run virtual machines, the composition of network interfaces will change. This may be related to the problem of the key operation. Ask the developer to make you a key to the real network card of the computer in this case.
