Hi,

Thanks for considering Aspose.

Pleaese make sure the validity of your license file and check:

Thank you.

Old Aspose.Excel license file has a problem under .Net2.0. I think it causes this problem.

For some external reasons, we don't provide Aspose.Excel any more. It's updated and changed to Aspose.Cells.

Please upgrade your application to Aspose.Cells and renew your subscription to get a new license file.
