Hello,
I am trying to update my Spire.PDF Platinum assemblies and am running into trouble. I use Spire.PDF and Spire.PDFViewer in a project and after I updated my references, I now get the exception Method Not Found: System.Drawing.Rectangle spr. I've read around and it seems to be the dlls I'm using aren't for Platinum. I know Spire.PDF is the correct one (4.4.6) but where do I get the PDFViewer for Platinum? The one I downloaded from your site doesn't seem to be for Platinum. Please Help.
