Hi,
Hi,
Hi,
Hi,
Thanks for your posting and considering Aspose.Cells.
Aspose.Excel is very old version. It is obsolete and no more supported. We also do not now support .NET 1.1. The minimum .NET framework version supported is 2.0. We are afraid, you will have to upgrade your application and use the latest version.
You might encounter some issues while upgrading, but you can always take the help of this forum. Once, you will upgrade your application, then next time it will be very easy to upgrade because we are now maintaining all Public API Changes of every new Aspose.Cells release. Please check the following links for your reference.
