Thanks for contacting support.
Since EasyGerb runs inside AutoCAD(as a 3rd party app), it doesn't have any user permission to store the "Numercal Cloud" license on your computer. To activate Numerical Cloud you need to activate either FAB 3000 or ACE Translator 3000 on your computer - first; then when using EasyGerb, it will automatically detect that Numerical Cloud has already been activated on your computer, and proceed. Here's our default instructions for setting up Numerical Cloud (please see the bottom note about EasyGerb). https://support.numericalinnovations.com/support/discussions/topics/14000008334
Thanks again, and please let me know your results.
