Hello,

Thanks for you inquiry.

You cannot use Spire.Doc and Spire.Xls in the same project at the same time due to conflicts between different Spire products. This is what causes this error.
In order to solve this, please completely remove Spire.Doc and Spire.Xls from the project first, and then install Spire.Office (a collection that contains almost all Spire product functions). Hope it helps you.
Sincerely,
Andy
