Null Rep Value while deploying outlook add in application that uses crystal reports.

[former_member695453]

I'm working on an outlook add in application that uses .Net Framework 4.0, Visual Studio 2010, Crystal Reports Version- 13.0.27.3480. I have built my setup using ClickOnce as the prerequisite. When I install the application on client machine, I see CRRuntimeEngine- 13.0.27.3480 installed, however I'm unable to open any reports. The error I see when I try to debug is that the Rep value is null. Can someone please suggest what I should be doing to resolve this or list down the steps to create the setup using Clickonce.

Install the runtime as alocal PC admin

Check permissions where the report is being loaded from.

Check permissions in Outlook.

Use ProcessMonitor to see where/when the issue is being blocked.

Add debug logic to your plug-in so you can trace the issue.

Open your plug-in debug mode and configure it to run in debug mode through outlook so you cna single step through your code and look for the report object value.
