That message states EasyGerb is not able to find your Numerical Cloud license.
Are you running AutoCAD as a different user? The Numerical Cloud license is stored per user (in the user Roaming Folder), so if you use the same computer but login as a different user - EasyGerb will no be able to find the license. If yes, please activate Numerical Cloud for the User account that has AutoCAD. https://numericalinnovations.freshdesk.com/support/discussions/topics/14000009099
My first recommendation would be to manually assign the Numerical Cloud folder in EasyGerb.
If problems persist, please let me know what AutoCAD version are you using? Include Platform details (i.e AutoCAD 2016 Windows 32-bit).
Note: Also, please make sure to install EasyGerb Version 7.0.3 (or higher). Previous versions did have an issue detecting the Numerical Cloud license.
I was able to install all three tools and activate the license. However, whenever I try to open easygerb in Autocad by first loading the app (APPLOAD) and typing in “easygerb” in the command line, the following error appears and Easygerb would not open.
Do you have any idea as to why it is keeping me from opening Easygerb?
