I downloaded the demo version and included the Spire.XLS dll along with the license dll in my solution. I get the following error at runtime:
Could not load file or assembly 'Spire.XLS, Version=5.8.9.3, Culture=neutral, PublicKeyToken=7fdbc5e92357a8da' or one of its dependencies. The system cannot find the file specified.
My solution is using the 3.5 framework running on Windows 7 64bit. I'm using VS 2010.
I like what I see in the demo projects and was hoping that I can use your product to convert xls to xlsx and xlsx to xls in my own project before I buy the product.
Any assistance would be appreciated.
