Hi Bhushan.. Thanks for the quick reply. I am sorry, I should have mentioned that I have done that already. That was one of the first things I checked. I installed SP15 on my development workstation and recompiled but had the same issue with the web viewer.. Not sure if this makes a difference but I am only having issues with the web viewer. My applications/projects I have for the windows platform run and generate reports with no issues.
Thanks
Casey
