Hi Brian,
I dont think the Report.LaunchViewer is intended to use the actual report file. If you were to return the Report location property, you would find has already been set to with the full path to your actual report.
What you could use instead in the Engine.LaunchExternalViewer(filePath)
The default OI will actual launch the viewer at the end of the execution, if External Report Viewer has been set to launch automically by using this API call.
This is done in the DisplayExternalViewerDialog which is launched via the menu item Configure | External Viewers...
There you will find a checkbox call 'Automatically Launch Default External Viewer'.
hope this helps
