We've been using a licensed copy of Aspose Cells 4.1.1 in several of our COM+ Dlls and some Windows Services since 2006.
Last April we purchased the Cells for .NET 7.1.2 upgrade and released this packaged with our other software as part of an update/patch.
However, one windows service keeps getting this error [Aspose.Cells.CellsException: You are using an evaluation copy and have opened files exceeding limitation.].
This service only uses Aspose.Cells.Workbook one stored procedure to perform an ExportDataTableAsString operation. Nothing else.
After lookng thorugh the forums, we believe we might be missing a call to SetLicense as described in your FAQs. We do call SetLicense in our other COM+ Dlls but we never needed to call it withing this Windows service.
Is this the solution for our issue and if it is, why do we need to do this all of a sudden while it was fine opening and exporting files before?
I've attached screencaps of the only lines wherein this windows service uses Aspose.Cells. We had to make these "AFTER" changes after we upgraded to 7.1.2 .NET.
We'd appreciate any input you have regarding the matter.
