I continue to get this error in VS 2005. It is part of a recently converted 2003 application to 2005. Any ideas what it is asking for? I did not see it anywhere in the properties of the grid or in the License xml.

Hi,

Some Aspose.Grid.Web earlier versions have this problem in vs.net 2005. Please upgrade to the latest version 1.7.4.

Let me know if you have any further questions.

Thank you.
