Hello,
Thanks for your inquiry.
We checked the records and found that you purchased the Standard Edition of Spire.XLS, it means your license is only valid for the Standard Edition (at present the latest version is
Spire.XLS for .NET Standard Edition Version:11.3). Please make sure you have downloaded the correct version for Standard Edition.
Besides, compared to the Pro Edition, the Standard Edition only can be used for .NET and doesn't support print and conversion function. If you need these functions, please contact our sales team (
sales@e-iceblue.com) to pay for the price difference to upgrade your license file from Spire.XLS Standard Edition to Pro Edition.
Sincerely,
Andy
E-iceblue support team
