I had a website with a Crystal Report Viewer written in asp.net 2.0/C# using Crystal Reports 10.2. I upgraded the site to 4.0 and now the print & export buttons do not work. The server I'm using has Crystal 10.2 and I have no control over upgrading it. I do not have Crystal 10.2 on my development computer. I do have version 13. How do I get the print & export buttons working?

Most of what I've seen online involves copying files from C:\Windows\Microsoft.NET\Framework\v4.0.30319\ASP.NETClientFiles\crystalreportviewers13. I've tried that and it led to a lot of missing references. When I tried to add those references, I encountered conflicts, probably because I was adding 13.0 references when I already had 10.2 references.

I would really like some step-by-step instructions on how to get the print & export buttons working. I've spent hours now adding this and that without success. Can anyone help me?
