When activating your ActiveReports license, this error occurs because the computer cannot connect to our licensing activation service.
Steps to Complete:
1. Open the command prompt as administrator. Run the License Manager using the following command: "GrapeCity.LicenseManager.exe /GetAuthenticationNumber /Product:"ActiveReports 12"
2. This will return the Authentication Number for the current machine. On a machine with internet connection, access http://sas.grapecity.com/activation and enter the Product Key and Authentication Number to get the License Key
3. Back on the first machine, run the below command to finish activating:
GrapeCity.LicenseManager.exe /Activate /Offline /Product:ProductName /ProductKey:YourProductKey /LicenseKey:YourLicenseKey
