  Hi,

  You could be utilising an invalid licence key in your application, which would result in the issue.

  Where you are specifying GC.Spread.Sheets.LicenseKey = GCExcel.LicenseKey = “YOUR KEY HERE>” in the application. You must substitute a valid SpreadJS License for the SpreadJS version you are using for “YOUR KEY HERE.”

  Regards,
