Bill, is the "new" version of the app still using WinForms? In other words, you're using WinForms but now using SSRS.

To the best of my awareness, the Report Viewer control still needs to be installed on the person's machine.

I am not 100% positive on this - it has been years since I did anything with WinForms, but I "think" you'll need this (or something like this)
